Poisoning of Alexander Litvinenko
Alexander Litvinenko was a former officer of the Russian Federal Security Service (FSB) and KGB, who fled from court prosecution in Russia and received political asylum in the United Kingdom. According to his wife and father, he was working for MI6 and MI5 after receiving the asylum.
In the UK, Litvinenko became a journalist for a Chechen separatist site, Chechenpress. Litvinenko wrote two books, Blowing up Russia: Terror from within and Lubyanka Criminal Group, where he accused the Russian secret services of staging Russian apartment bombings and other terrorism acts to bring Vladimir Putin to power.
On 1 November 2006, Litvinenko suddenly fell ill and was hospitalized. He died three weeks later, becoming the first confirmed victim of lethal polonium-210-induced acute radiation syndrome. Litvinenko's allegations about the misdeeds of the FSB and his public deathbed accusations that Russian president Vladimir Putin was behind his unusual malady resulted in worldwide media coverage.
Subsequent investigations by British authorities into the circumstances of Litvinenko's death led to serious diplomatic difficulties between the British and Russian governments. Unofficially, British authorities asserted that "we are 100% sure who administered the poison, where and how", but they did not disclose their evidence in the interest of a future trial. The main suspect in the case, a former officer of the Russian Federal Protective Service (FSO), Andrey Lugovoy, remains in Russia. As a member of the Duma, he now enjoys immunity from prosecution. Before he was elected to the Duma, the British government tried to extradite him without success.
At the same time, Litvinenko's father, now residing in Italy, believes Boris Berezovsky and Alexander Goldfarb were behind the murder. Berezovsky was found dead at his home in England on 23 March 2013.

Alexander Litvinenko was a former officer of the Russian Federal Security service who escaped prosecution in Russia and received political asylum in Great Britain. In his books, Blowing up Russia: Terror from Within and Lubyanka Criminal Group, Litvinenko described Russian president Vladimir Putin's rise to power as a coup d'état organised by the FSB. He alleged that a key element of FSB's strategy was to frighten Russians by bombing apartment buildings in Moscow and other Russian cities. He accused Russian secret services of having arranged the Moscow theater hostage crisis, through their Chechen agent provocateur, and having organised the 1999 Armenian parliament shooting. He also stated that terrorist Ayman al-Zawahiri was under FSB control when he visited Russia in 1997.
Illness and poisoning
On 1 November 2006, Litvinenko suddenly fell ill. Earlier that day he had met two former KGB officers, Andrey Lugovoy and Dmitry Kovtun. Lugovoy is a former bodyguard of Russian ex-Prime Minister Yegor Gaidar (also reportedly poisoned in November 2006) and former chief of security for the Russian TV channel ORT. Kovtun is now a businessman. Litvinenko had also had lunch at Itsu, a sushi restaurant on Piccadilly in London, with an Italian officer and "nuclear expert", Mario Scaramella, to whom he reportedly made allegations regarding Romano Prodi's connections with the KGB. Scaramella, attached to the Mitrokhin Commission investigating KGB penetration of Italian politics, claimed to have information on the death of Anna Politkovskaya, 48, a journalist who was killed at her Moscow apartment in October 2006. He passed Litvinenko papers supposedly concerning her fate. On 20 November, it was reported that Scaramella had gone into hiding and feared for his life.
For several days after 1 November, Litvinenko experienced severe diarrhea and vomiting. At one point, he could not walk without assistance. As the pain intensified, Litvinenko asked his wife to call an ambulance for assistance. For several weeks, Litvinenko's condition worsened as doctors searched for the cause of the illness. Surrounded by friends, Litvinenko began to become physically weak, and spent periods unconscious. A photograph was taken of Litvinenko on his deathbed and released to the public. "I want the world to see what they did to me," Litvinenko said.
Shortly after his death, the UK's Health Protection Agency (HPA) stated that tests had established that Litvinenko had significant amounts of the radionuclide polonium-210 (210Po) in his body. British and US government sources both said the use of 210Po as a poison had never been documented before, and this was probably the first time a person has been tested for the presence of 210Po in his or her body. The poison was in Litvinenko's teacup; which he had just drank tea out of. People who had contact with Litvinenko may also have been exposed to radiation.
Polonium was identified only after Litvinenko's death, on 23 November. Doctors and Scotland Yard investigators could not detect polonium earlier because it does not emit gamma rays, which are encountered with most radioactive isotopes. Unlike most common radiation sources, polonium-210 emits only alpha particles that do not penetrate even a sheet of paper or the epidermis of human skin, thus being invisible to normal radiation detectors in this case. Hospitals only have equipment to detect gamma rays. Both gamma rays and alpha particles are classified as ionizing radiation which can cause radiation damage. An alpha-emitting substance can cause significant damage only if ingested or inhaled, acting on living cells like a short-range weapon. Litvinenko was tested for alpha-emitters using special equipment only hours before his death.
Po-210 concentration in the body of Litvinenko
The symptoms seen in Litvinenko appeared consistent with an administered activity of approximately 2 GBq (50 mCi) which corresponds to about 10 micrograms of 210Po. That is 200 times the median lethal dose of around 238 μCi or 50 nanograms in the case of ingestion.
Thallium – initial hypothesis
Scotland Yard initially investigated claims that Litvinenko was poisoned with thallium. It was reported that early tests appeared to confirm the presence of the poison. Among the distinctive effects of thallium poisoning are hair loss and damage to peripheral nerves, and a photograph of Litvinenko in hospital, released to the media on his behalf, indeed showed his hair to have fallen out. Litvinenko attributed his initial survival to his cardiovascular fitness and swift medical treatment. It was later suggested a radioactive isotope of thallium might have been used to poison Litvinenko. Dr. Amit Nathwani, one of Litvinenko's physicians, said "His symptoms are slightly odd for thallium poisoning, and the chemical levels of thallium we were able to detect are not the kind of levels you'd see in toxicity." Litvinenko's condition deteriorated, and he was moved into intensive care on 20 November. Hours before his death, three unidentified circular-shaped objects were found in his stomach via an X-ray scan. It is thought these objects were almost certainly shadows caused by the presence of Prussian blue, the treatment he had been given for thallium poisoning.
Death and last statement
Late on 22 November, Litvinenko's heart failed; the official time of death was 9:21 pm at University College Hospital in London.
The autopsy took place on 1 December. Litvinenko had ingested polonium-210, a poisonous radioactive isotope. Mario Scaramella, who had eaten with Litvinenko, reported that doctors had told him the body had five times the lethal dose of polonium-210. Litvinenko's funeral took place on 7 December at the Central London mosque, after which his body was buried at Highgate Cemetery in North London.
In his last statement he said about Putin:
...this may be the time to say one or two things to the person responsible for my present condition. You may succeed in silencing me but that silence comes at a price. You have shown yourself to be as barbaric and ruthless as your most hostile critics have claimed. You have shown yourself to have no respect for life, liberty or any civilised value. You have shown yourself to be unworthy of your office, to be unworthy of the trust of civilised men and women. You may succeed in silencing one man but the howl of protest from around the world will reverberate, Mr Putin, in your ears for the rest of your life. May God forgive you for what you have done, not only to me but to beloved Russia and its people.
Greater London's Metropolitan Police Service Terrorism Unit has been investigating the poisoning and death. The head of the Counter-Terrorism Unit, Deputy Assistant Commissioner Peter Clarke, stated the police "will trace possible witnesses, examine Mr. Litvinenko's movements at relevant times, including when he first became ill and identify people he may have met. There will also be an extensive examination of CCTV footage." The United Kingdom Government COBRA committee met to discuss the investigation. Richard Kolko from the United States FBI stated "when requested by other nations, we provide assistance" – referring to the FBI now joining the investigation for their expertise on radioactive weapons. The Metropolitan Police announced on 6 December 2006 that it was treating Litvinenko's death as murder. Interpol has also joined the investigation, providing "speedy exchange of information" between British, Russian and German police.
Detectives traced three distinct polonium trails in and out of London. The trails were left by Litvinenko, Andrey Lugovoy and Dmitry Kovtun. The patterns and levels of radioactivity they left behind suggested that Litvinenko ingested polonium, whereas Lugovoy and Kovtun handled it directly. The human body dilutes polonium before excreting it in sweat, which results in a reduced radioactivity level. There were also traces of Po-210 found at the Hey Jo/Abracadabra bar, Dar Marrakesh restaurant, and Lambeth-Mercedes taxis.
The poisoning of Litvinenko took place at around 5 pm of 1 November in the Millennium Hotel in Grosvenor Square. The bus he travelled in to the hotel had no signs of radioactivity – but large amounts had been detected at the hotel. Polonium was subsequently found in a fourth-floor room and in a cup in the Pine Bar at the hotel. After the Millennium bar, Litvinenko stopped at the office of Boris Berezovsky. He used a fax machine, where the radioactivity was found later. At 6 pm Akhmed Zakayev picked Litvinenko up and brought him home to Muswell Hill. The amount of radioactivity left by Litvinenko in the car was so significant, the car was rendered unusable. Everything that he touched at home during the next three days was contaminated. His family was unable to return to the house even six months later. His wife was tested positive for ingesting polonium but did not leave a secondary trail behind her. This suggested that anyone who left a trail could not have picked up the polonium from Litvinenko (possibly, including Lugovoy and Kovtun).
Besides Litvinenko, only two people left the polonium trails: Lugovoy and Kovtun who were school friends and worked previously for Russian intelligence in the KGB and the GRU respectively. These people handled the radioactive material directly and did not ingest it, because they left more significant traces of polonium than Litvinenko.
Lugovoy and Kovtun met Litvinenko in the Millennium hotel bar twice, on 1 November (when the poisoning took place), and earlier, on 16 October. Trails left by Lugovoy and Kovtun started on 16 October, in the same sushi bar where Litvinenko was poisoned later, but at a different table. It was assumed that their first meeting with Litvinenko was either a rehearsal of the future poisoning, or an unsuccessful attempt of the poisoning.
Traces left by Lugovoy were also found in the office of Berezovsky that he visited on 31 October, a day before his second meeting with Litvinenko. Traces left by Kovtun were found in Hamburg, Germany. He left them on his way to London on 28 October. The traces were found in passenger jets BA875 and BA873 from Moscow to Heathrow on 25 and 31 October, as well as flights BA872 and BA874 from Heathrow to Moscow on 28 October and 3 November.
Andrey Lugovoy has said he flew from London to Moscow on a 3 November flight. He stated he arrived in London on 31 October to attend the football match between Arsenal and CSKA Moscow on 1 November. When the news broke that a radioactive substance had been used to murder Litvinenko, a team of scientists rushed to find out how far the contamination had spread. It led them on a trail involving hundreds of people and dozens of locations.
British Airways later published a list of 221 flights of the contaminated aircraft, involving around 33,000 passengers, and advised those potentially affected to contact the UK Department of Health for help. On 5 December they issued an email to all of their customers, informing them that the aircraft had all been declared safe by the UK's Health Protection Agency and would be re-entering service.
British extradition request
British authorities investigated the death and it was reported on 1 December that scientists at the Atomic Weapons Establishment had traced the source of the polonium to a nuclear power plant in Russia. On 3 December, reports stated that Britain has demanded the right to speak to at least five Russians implicated in Litvinenko's death, and Russian Foreign Minister Sergey Lavrov asserted that Moscow was willing to answer "concrete questions." Russian Prosecutor-General Yuri Chaika said on Tuesday, 5 December that any Russian citizen who may be charged in the poisoning will be tried in Russia, not Britain. Moreover, Chaika stated that UK detectives may ask questions to Russian citizens only in the presence of Russian prosecutors.
On 28 May 2007 the British Foreign Office submitted a formal request to the Russian Government for the extradition of Andrey Lugovoy to the UK to face criminal charges relating to Litvinenko's murder.
The Russian General Prosecutor's Office declined to extradite Lugovoy, citing that extradition of citizens is not allowed under the Russian constitution (Article 61 of the Constitution of Russia). Russian authorities later said that Britain has not handed over any evidence against Lugovoy. Professor Daniel Tarschys, former Secretary General of the Council of Europe, commented that the Russian Constitution actually "opens the door" for the extradition, and Russia ratified three international treaties on extradition (on 10 December 1999); namely, the European Convention on Extradition and two Additional Protocols to it. Yury Fedotov, Ambassador of the Russian Federation, pointed out that when the Russian Federation ratified the European Convention on Extradition it entered a declaration concerning Article 6 in these terms: "The Russian Federation declares that in accordance with Article 61 (part 1) of the Constitution of the Russian Federation, a citizen of the Russian Federation may not be extradited to another state." The same protections are extended to the citizens of France and Germany, both of which refuse to extradite their citizens.
On 7 July 2008, a British security source told the BBC's Newsnight programme: "We very strongly believe the Litvinenko case to have had some state involvement. There are very strong indications." The British government claimed that no intelligence or security officials were authorised to comment on the case.
On 2 March 2007, Paul Joyal, a former director of security for the U.S. Senate intelligence committee, who the previous weekend alleged on national television that the Kremlin was involved in the poisoning of Litvinenko, was shot near his Maryland home. An FBI spokesman said the agency was "assisting" the police investigation into the shooting. Police would not confirm details of the shooting or of the condition of Joyal. A person familiar with the case said he was in critical condition in hospital. It was reported that while there were no indications that the shooting was linked to the Litvinenko case, it is unusual for the FBI to get involved in a local shooting incident. A person familiar with the situation said NBC had hired bodyguards for some of the journalists involved in the program.
Sources and production of polonium
A freelance killer would probably not be able to manufacture polonium from commercially available products in the amounts used for Litvinenko's poisoning, because more than microscopic amounts of polonium can only be produced in state-regulated nuclear reactors.
Ninety seven percent of the world's legal polonium-210 (210Po) production occurs in Russia in RBMK reactors. About 85 grams (450,000 Ci) are produced by Russia annually. According to Sergei Kiriyenko, the head of Russia's state atomic energy agency, RosAtom, all of it goes to U.S. companies through a single authorized supplier. The production of polonium starts from bombardment of bismuth (209Bi) with neutrons at the Ozersk nuclear reactor, near the city of Chelyabinsk in Russia. The product is then transferred to the Avangard Electromechanical Plant in the closed city of Sarov. This of course does not exclude the possibility that the polonium that killed Litvinenko was imported by a licensed commercial distributor, but no one—including the Russian government—has proposed that this is likely, particularly in regard to the radiation detected on the British Airways passenger jets travelling between Moscow and London. Russian investigators have said they could not identify the source of polonium.
Polonium-210 has a half-life of 138 days and decays to the stable daughter isotope of lead, 206Pb. Therefore the source is reduced to about one sixteenth of its original radioactivity about 18 months after production. By measuring the proportion of polonium and lead in a sample, one can establish the production date of polonium. The analysis of impurities in the polonium (a kind of "finger print") allows identification of the place of production. It is assumed by Litvinenko's wife and his close confidant that British investigators were able to identify the place and time of production of polonium used to poison Litvinenko, but their findings remain unpublished.
Possible motivation for using polonium-210
Philip Walker, professor of physics at the University of Surrey said: "This seems to have been a substance carefully chosen for its ability to be hard to detect in a person who has ingested it." Oleg Gordievsky, the most senior KGB agent ever to defect to Britain, made a similar comment that Litvinenko's assassination was carefully prepared and rehearsed by Russian secret services, but the poisoners were unaware that technology existed to detect traces left by polonium-210: "Did you know that polonium-210 leaves traces? I didn’t. And no one did. ...what they didn’t know was that this equipment, this technology exists in the West – they didn’t know that, and that was where they miscalculated."
Nick Priest, a nuclear scientist and expert on polonium who has worked at most of Russia's nuclear research facilities, says that although the execution of the plot was a "bout of stupidity", the choice of polonium was a "stroke of genius". He says: "the choice of poison was genius in that polonium, carried in a vial in water, can be carried in a pocket through airport screening devices without setting off any alarms", adding, "once administered, the polonium creates symptoms that don't suggest poison for days, allowing time for the perpetrator to make a getaway." Priest asserts that "whoever did it was probably not an expert in radiation protection, so they probably didn't realize how much contamination you can get just by opening the top (of the vial) and closing it again. With the right equipment, you can detect just one count per second".
Filmmaker and friend of Litvinenko, Andrei Nekrasov, has suggested that the poison was "sadistically designed to trigger a slow, tortuous and spectacular demise". Expert on Russia Paul Joyal suggested that "A message has been communicated to anyone who wants to speak out against the Kremlin.... If you do, no matter who you are, where you are, we will find you, and we will silence you, in the most horrible way possible".
Many theories of Litvinenko poisoning circulated after his death. Many circumstances led to suspicion that he was killed by the Russian secret service. Viktor Ilyukhin, a deputy chairman of the Russian Parliament's security committee for the Communist Party of the Russian Federation, said that he "can’t exclude that possibility" He apparently referred to a recent Russian counter-terrorism law that gives the President the right to order such actions. An investigator of the Russian apartment bombings, Mikhail Trepashkin wrote in a letter from prison that an FSB team had organised in 2002 to kill Litvinenko. He also reported FSB plans to kill relatives of Litvinenko in Moscow in 2002, although these have not been carried out. State Duma member Sergei Abeltsev commented on 24 November 2006: said: "The deserved punishment reached the traitor. I am confident that this terrible death will be a serious warning to traitors of all colors, wherever they are located: In Russia, they do not pardon treachery. I would recommend citizen Berezovsky to avoid any food at the commemoration for his accomplice Litvinenko."
Many publications in Russian media suggested that the death of Litvinenko was connected to Boris Berezovsky. Former FSB chief Nikolay Kovalyov, for whom Litvinenko worked, said that the incident "looks like [the] hand of Berezovsky. I am sure that no kind of intelligence services participated." This involvement of Berezovsky was alleged by numerous Russian television shows.
An explanation put forward by the Russian Government appeared to be that the deaths of Litvinenko and Politkovskaya were intended to embarrass President Putin. Other theories included involvement of rogue FSB members or suggestions that Litvinenko was killed because of his research of certain Russian corporations or state officials, or as a political intrigue to undermine president Putin.
- Andrey Lugovoy
- A former Federal Protective Service of Russia officer and millionaire who met with Litvinenko on the day he fell ill (1 November). He had visited London at least three times in the month before Litvinenko's death and met with the victim four times. Traces of polonium-210 have been discovered in all three hotels where Lugovoy stayed after flying to London on 16 October, and in the Pescatori restaurant in Dover Street, Mayfair, where Lugovoy is understood to have dined before 1 November; and aboard two aircraft on which he had travelled. He has declined to say whether he had been contaminated with polonium-210. The Crown Prosecution Service has charged him with murder and has sent an extradition request to Russia that includes a summary of the evidence, but the only third party to have seen the extradition request, American journalist Edward Epstein, has described the substantiation as "embarrassingly thin".
- Dmitry Kovtun
- A Russian businessman and ex-KGB agent who met Litvinenko in London first in mid-October and then on 1 November, the day Litvinenko fell ill. On 7 December Kovtun was hospitalized, with some sources initially reporting him to be in coma. On 9 December, German police found traces of radiation at a Hamburg flat used by Kovtun. The following day, 10 December, German investigators identified the detected material as polonium-210 and clarified that the substance was found where Kovtun had slept the night before departing for London. British police also report having detected polonium on the plane in which Kovtun travelled from Moscow. Three other points in Hamburg were identified as contaminated with the same substance. On 12 December Kovtun told Russia's Channel One TV that his "health was improving".
- Kovtun was under investigation by German detectives for suspected plutonium smuggling into Germany in October. Germany dropped the case against Kovtun on November 2009 
- Vyacheslav Sokolenko
- A business partner of Andrey Lugovoy.
- The Times stated that the police have identified the man they believe may have poisoned Litvinenko with a fatal polonium dose in a cup of tea on the fourth-floor room at the Millennium Hotel to discuss a business deal with Dmitry Kovtun and Andrey Lugovoy before going to the bar. These three men were joined in the room later by the mystery figure who was introduced as Vladislav, a man, who could help Litvinenko win a lucrative contract with a Moscow-based private security firm.
- Vladislav is said to have arrived in London from Hamburg on 1 November on the same flight as Dmitry Kovtun. His image is recorded by security cameras at Heathrow airport on arrival. He is described as being in his early 30s, tall, strong, with short black hair and Central Asian features. Oleg Gordievsky, an ex-KGB agent, has said that this man was believed to have used a Lithuanian or Slovak passport, and that he left the country using another EU passport. He has also said Vladislav started his preparations in early 2006, "some time between February and April", that he "travelled to London, walked everywhere, and studied everything."
- Businessman and politician Boris Berezovsky said in a police interview that "Sasha mentioned some person who he met at Millennium Hotel", but would not "remember whether [his name] was Vladimir or Vyacheslav." Litvinenko's friend Alex Goldfarb writes that according to Litvinenko, "Lugovoy brought along a man whom [Litvinenko] had never seen before and who had 'the eyes of a killer.'"
- Igor the Assassin
- The code name for a former KGB assassin. He is said to be a former Spetznaz officer born in 1960 who is a Judo master and walks with a slight limp. He allegedly speaks perfect English and Portuguese and may be the same person who served Litvinenko tea in the London hotel room.
- Yegor Gaidar
- The sudden illness of Yegor Gaidar in Ireland on 24 November 2006, the day of Litvinenko's death, has been linked to his visit to the restaurant where polonium was present and is being investigated as part of the overall investigation in the UK and Ireland., Other observers noted he was probably poisoned after drinking a strange-tasting cup of tea. Gaidar was taken to hospital; doctors said his condition is not life-threatening and that he will recover. This incident was similar to the poisoning of Anna Politkovskaya on a flight to Beslan. After poisoning, Gaidar claimed that it was enemies of Kremlin who tried to poison him.
- Mario Scaramella
- The United Kingdom's Health Protection Agency (HPA) announced that significant quantities of polonium-210 had been found in Mario Scaramella although his health was found to be normal. He has been admitted to hospital for tests and monitoring. Doctors say that Scaramella was exposed to a much lower level of polonium-210 than Litvinenko had been exposed to, and that preliminary tests found "no evidence of radiation toxicity". According to the 6 pm Channel 4 (9 December 2006) news the intake of polonium he suffered will only result in a dose of 1 mSv. This will lead to a 1 in 20000 chance of cancer. According to The Independent, Scaramella alleged that Litvinenko was involved in smuggling radioactive material to Zürich in 2000.
- Boris Volodarsky, a KGB defector residing in London, stated that Evgeni Limarev, another former KGB officer residing in France, continued collaboration with FSB, infiltrated Litvinenko's and Scaramella's circles of trust and misinformed the latter.
- Igor Ponomarev
- Igor Ponomarev was a Russian diplomat whose death was named a possible murder by Paolo Guzzanti
- Marina Litvinenko
- UK reports state Litvinenko's widow tested positive for polonium, though she is not seriously ill. The Ashdown Park hotel in Sussex has been evacuated as a precaution, possibly to do with Scaramella's previous visit there. According to the 6 pm Channel 4 (9 December 2006) news the intake of polonium she suffered will only result in a dose of 100 mSv. This will lead to a 1 in 200 chance of cancer.
- Akhmed Zakayev
- The forensic investigation also includes the silver Mercedes by Litvinenko's home believed to be owned by his close friend and neighbour Akhmed Zakayev, then foreign minister of the separatist government in exile of Ichkeria. Reports now state that traces of radioactive material were found in the vehicle.
- Bar staff
- Some of the bar staff at the hotel where the polonium contaminated teacup was found were discovered to have suffered an intake of polonium (dose in the range of 10s of mSv). These people include Norberto Andrade, the head barman of the bar and a long-time (27 years) worker at the hotel. He has described the situation thus:
- "When I was delivering gin and tonic to the table, I was obstructed. I couldn't see what was happening, but it seemed very deliberate to create a distraction. It made it difficult to put the drink down."
- "It was the only moment when the situation seemed unfriendly and something went on at that point. I think the polonium was sprayed into the teapot. There was contamination found on the picture above where Mr Litvinenko had been sitting and all over the table, chair and floor, so it must have been a spray."
- "When I poured the remains of the teapot into the sink, the tea looked more yellow than usual and was thicker – it looked gooey."
- "I scooped it out of the sink and threw it into the bin. I was so lucky I didn't put my fingers into my mouth, or scratch my eye as I could have got this poison inside me."
- 7 June 1994: A remote-controlled bomb detonated aiming at chauffeured Mercedes 600 with oligarch Boris Berezovsky and his bodyguard in the rear seat. The driver died but Berezovsky left the car unscathed. Litvinenko, then with the organized-crime unit of the FSB, was an investigating officer of the assassination attempt. The case was never solved, but it was at this point that Litvinenko befriended Berezovsky.

- 7 December: Russian Office of the Prosecutor General has opened a criminal case over poisoning of Litvinenko and Kovtun by the articles "Murder committed in a way endangering the general public" (убийство, совершенное общеопасным способом) and "Attempted murder of two or more persons committed in a way endangering the general public".
- 8 December: Kovtun is reported to be in coma.
- 9 December: German police find traces of radiation at Hamburg flat used by Kovtun.
- 9 December: UK police identify a single cup at the Pines Bar in the Millennium Hotel in Mayfair which was almost certainly the one used to administer the poison.
- 11 December: Andrey Lugovoy is interrogated in Moscow by UK Scotland Yard and General Procurator's office of the Russian Federation. He refuses to reveal any information concerning the interrogation.
- 12 December: Dmitry Kovtun tells a Russian TV station that his "health [is] improving".
- 24 December: Mario Scaramella was arrested in Naples on his return from London, on apparently unrelated charges.
- 27 December: Prosecutor General of Russia Yury Chaika accused Leonid Nevzlin, a former Vice President of Yukos, exiled in Israel and wanted by Russian authorities for a long time, of involvement in the poisoning, a charge dismissed by the latter as a nonsense.
- 5 February: Boris Berezovsky told the BBC that on his deathbed, Litvinenko said that Lugovoy was responsible for his poisoning.
- 6 February: The text of a letter written by Litvinenko's widow on 31 January to Putin, demanding that Putin work with British authorities on solving the case, was released.
- 8 February 2007: Update to HPA (Health Protection Agency) investigation of polonium 210 incident.
- 21 May: Sir Ken Macdonald QC (Director of Public Prosecutions of England and Wales ) say that Lugovoy, should face trial for the "grave crime" of murdering Litvinenko.
- 22 May: Macdonald announces that Britain will seek extradition of Lugovoy and attempt to charge him with murdering Litvinenko. The Russian government states that they will not allow the extradition of any Russian citizens.
- 28 May: The British Foreign Office formally submits a request to the Russian Government for the extradition of Lugovoy to the UK to face criminal charges.
Extradition requests had been granted in the past (For example in 2002 Murad Garabayev has been handed to Turkmenistan., Garabayev's extradition was later found unlawful by the Russian courts and he was awarded 20,000 Euros in damages to be paid by the Russian government by the European Court of Human Rights.) Article 63 does not explicitly mention Russian citizens, and therefore does not apply to them, but only to foreign nationals living in Russia. Article 61 supersedes it for the people holding the Russian citizenship.
- 31 May: Lugovoy held a news conference at which he accused MI6 of attempting to recruit him and blamed either MI6, the Russian mafia, or fugitive Kremlin opponent Boris Berezovsky for the killing.
- 16 July: The British Foreign Office confirms that, as a result of Russia's refusal to extradite Lugovoy, four Russian diplomats are to be expelled from the Russian Embassy in London.

Such claims have been denied by Marina Litvinenko and Oleg Gordievsky.
- In the 16 December 2008 interview, when asked by the Spanish newspaper El País if Litvinenko could have been killed in the interests of the Russian state, Lugovoy – wanted by British police on suspicion of the murder of Litvinenko – replied that he would order the assassination of anyone, for example, President Saakashvili of Georgia and the KGB defector Gordievsky, in the interests of the Russian state.
Comparisons to other deaths
Deaths from ingesting radioactive materials
According to the IAEA in 1960 a person ingested 74 MBq of radium (assumed to be 226Ra) and this person died four years later. Harold McCluskey survived 11 years (eventually dying from cardio respiratory failure) after an intake of at least 37 MBq of 241Am (He was exposed in 1976). It is estimated that he suffered doses of 18 Gy to his bone mass, 520 Gy to the bone surface, 8 Gy to the liver and 1.6 Gy to the lungs; it is also claimed that a post mortem examination revealed no signs of cancer in his body. The October 1983 issue of the journal Health Physics was dedicated to McCluskey, and subsequent papers about him appeared in the September 1995 issue.
Similar suspicious deaths and poisonings
Comparisons have been made to the alleged 2004 poisoning of Viktor Yushchenko, the alleged 2003 poisoning of Yuri Shchekochikhin and the fatal 1978 poisoning of the journalist Georgi Markov by the Bulgarian Committee for State Security. The incident with Litvinenko has also attracted comparisons to the poisoning by radioactive (unconfirmed) thallium of KGB defector Nikolay Khokhlov and journalist Shchekochikhin of Novaya Gazeta (the Novaya Gazeta interview with the former, coincidentally, prepared by Russian journalist Anna Politkovskaya, who was later found shot to death in her apartment building). Like Litvinenko, Shchekochikhin had investigated the Russian apartment bombings (he was a member of the Kovalev Commission that hired Litvinenko's friend Mikhail Trepashkin as a legal counsel).
KGB defector and British agent Oleg Gordievsky believes the murders of Zelimkhan Yandarbiev, Shchekochikhin, and Politkovskaya and the incident with Litvinenko show that FSB has returned to the practice of political assassinations, which were conducted in the past by Thirteenth Department of the KGB. A comparison was also made with Roman Tsepov who was responsible for personal protection of Anatoly Sobchak and Putin, and who died in Russia in 2004 from poisoning by an unknown radioactive substance.

- Johns Hopkins University and Hoover Institute scholar David Satter described this controversy in the United States House of Representatives: "With Yeltsin and his family facing possible criminal prosecution, however, a plan was put into motion to put in place a successor who would guarantee that Yeltsin and his family would be safe from prosecution and the criminal division of property in the country would not be subject to reexamination. For "Operation Successor" to succeed, however, it was necessary to have a massive provocation. In my view, this provocation was the bombing in September 1999 of the apartment building bombings in Moscow, Buinaksk, and Volgodonsk. In the aftermath of these attacks, which claimed 300 lives, a new war was launched against Chechnya. Putin, the newly appointed prime minister who was put in charge of that war, achieved overnight popularity. Yeltsin resigned early. Putin was elected president and his first act was to guarantee Yeltsin immunity from prosecution."

According to Preobrazhenskiy, "At that time, Litvinenko was the Head of the Subdivision for Internationally Wanted Terrorists of the First Department of the Operative-Inquiry Directorate of the FSB Anti-Terrorist Department. He was ordered to undertake the delicate mission of securing Al-Zawahiri from unintentional disclosure by the Russian police. Though Al-Zawahiri had been brought to Russia by the FSB using a false passport, it was still possible for the police to learn about his arrival and report to Moscow for verification. Such a process could disclose Al-Zawahiri as an FSB collaborator. In order to prevent this, Litvinenko visited a group of the highly placed police officers to notify them in advance."
