Guy Lynn is a British investigative reporter for the BBC.
He was a contributing author to "Investigative Journalism: Dead or Alive", published in 2011 by Abramis.
Lynn's undercover report on fake vet Leonard French, who controlled much of the UK's illegal black market in animal medicine, led directly to the imprisonment of French on 20 August 2007 for twelve months at Lincoln crown court. French's attempt to overturn the sentence was rejected by the court of appeal in 2008.
In August 2009, a TV report exposing discrimination against migrant workers in Boston led to follow up investigations by the Equality and Human Rights Commission and won "Best Nations and Regions coverage" at the Amnesty International UK Media Awards of 2010.
Amnesty International described it as having received "unprecedented national exposure, making waves from Poland to China. This was outstanding, shocking and emblematic of a deeper malaise in UK society."
In 2012, Ukraine's top Olympic official – the secretary general of the Ukrainian Olympic Committee – Volodymyr Geraschenko, was suspended and later resigned after Lynn's undercover report where Geraschenko offered to illegally sell tickets on the black market prior to the London Olympics.
Lynn also travelled to Indonesia where he posed as a coffee importer and uncovered animal cruelty behind a luxury coffee made out of civet cat droppings. Following the programme's broadcast Harrods removed the civet cat coffee from its shelves.
In 2015 and 2016, various reports for the BBC resulted in the lifelong suspension of a large number of high street pharmacists implicated in an investigation about the illegal sales of prescription only medicine. There were several appeals which were upheld by the UK's High Court of Justice
Between 2000 and 2003, Lynn was based in the Middle East, covering the intifada and 11 September for ABC TV news. He wrote and directed the documentary series "Ordinary People", broadcast on several TV stations and co-authored the five-part TV documentary series "100 Years of Terror" for Emmy award winning production company, Set Productions.
