The next general election in the United Kingdom is scheduled to be held on 5 May 2022 under the Fixed-term Parliaments Act 2011. The election may be held at an earlier date in the event of an early election motion being passed by a super-majority of two-thirds in the House of Commons, or a vote of no confidence in the government which is not followed by a vote of confidence within 14 days.
Each parliamentary constituency of the United Kingdom elects one MP to the House of Commons using the "first past the post" system.
- on the Electoral Register;
- aged 18 or over on polling day;
- a British, Irish or Commonwealth citizen;
- a resident at an address in the United Kingdom (or a British citizen living abroad who has been registered to vote in the UK in the last 15 years);[n 8] and
- not legally excluded from voting (for example a convicted person detained in prison or a mental hospital, or unlawfully at large if he/she would otherwise have been detained, or a person found guilty of certain corrupt or illegal practices) or disqualified from voting (peers sitting in the House of Lords).
Individuals must be registered to vote by midnight twelve working days before polling day. Anyone who qualifies as an anonymous elector has until midnight six working days before polling day to register.[n 9] A person who has two homes (such as a university student who has a term-time address and lives at home during holidays) may be able to register to vote at both addresses as long as they are not in the same electoral area, but can only vote in one constituency at the general election.
It is current UK government policy to pass a law removing the 15-year limit on expatriate Britons voting before the next general election takes place, as mentioned in the 2017 Conservative Party manifesto, which stated (page 42) "We will legislate for votes for life for British overseas electors".
The postponed Sixth Periodic Review of Westminster constituencies proposed reducing the number of constituencies from 650 to 600. In April 2016, each of the four parliamentary Boundary Commissions of the United Kingdom recommenced the review process, to be implemented in 2018.
Date of the election
The Fixed-term Parliaments Act 2011 introduced fixed-term parliaments to the United Kingdom, with elections scheduled on the first Thursday in May of the fifth year after the previous general election.
Removing the power of the monarch, on advice of the prime minister, to dissolve parliament before its five-year maximum length, the act permits early dissolution if the House of Commons votes by a two-thirds supermajority, as occurred in the 2017 general election. Parliament is also dissolved if a government loses a vote of no confidence by a simple majority and a new government is not formed within 14 days.
The next general election is due to take place on 5 May 2022. Under the Electoral Registration and Administration Act 2013 parliament would be dissolved 25 working days before this date on 28 March 2022. Under the Fixed-term Parliaments Act the prime minister may schedule polling day up to two months after 5 May 2022, subject to approval by both Houses.
The Conservative Party manifesto at the 2017 general election proposed repealing the Fixed-term Parliaments Act 2011.
Contesting political parties and candidates
Most candidates are representatives of a political party, which must be registered with the Electoral Commission's Register of Political Parties. Candidates who do not belong to a registered party can use an "independent" label, or no label at all.
The Conservative Party and Labour Party have been the two biggest political parties, and have supplied every Prime Minister, since 1922 (with the exception of Ramsay MacDonald, who served as Prime Minister from 1931 to 1935 as a member of the National Labour Organisation).
Parties in the tables below are sorted by their results in the 2017 general election.
The leader of the party commanding a majority of support in the House of Commons is the person who is called on by the monarch to form a government as Prime Minister, while the leader of the largest party not in government becomes the Leader of the Opposition. Other parties also form shadow ministerial teams. The leaders of the SNP and Plaid Cymru are not members of parliament, but instead members of their respective devolved legislatures, and so these parties have separate leaders in the House of Commons (Ian Blackford for the SNP and Liz Saville Roberts in the case of Plaid Cymru).
|Party||Party leader(s)||Leader since||Leader's seat||Last election|
| % of
|Conservative Party||Theresa May||July 2016||Maidenhead||42.4%||317|
|Labour Party||Jeremy Corbyn||September 2015||Islington North||40.0%||262|
|Scottish National Party||Nicola Sturgeon||November 2014||None[n 10]||3.0%||35|
|Liberal Democrats||Vince Cable||July 2017||Twickenham||7.4%||12|
|Plaid Cymru||Leanne Wood||March 2012||None[n 11]||0.5%||4|
|Green Party (England & Wales)||Caroline Lucas
|September 2016||Brighton Pavilion
Tim Farron announced his departure as Liberal Democrat leader shortly after the June 2017 election, staying on in a caretaker basis pending the Liberal Democrats leadership election. He was replaced by Vince Cable.
While a number of UK parties organise in Northern Ireland (e.g. Labour Party in Northern Ireland, but they do not field candidates) and field candidates for election (e.g., Conservative, UKIP, Green), the main Northern Ireland parties differ to the rest of the UK.
|Party||Leader(s)||Leader since||Leader's seat||Last election|
|Democratic Unionist Party||Arlene Foster||December 2015||None[n 7]||36.0%||10|
|Sinn Féin||Mary Lou McDonald||10 February 2018||None[n 5]||29.4%||7|
|Social Democratic & Labour Party||Colum Eastwood||November 2015||None[n 12]||11.7%||0|
|Ulster Unionist Party||Robin Swann||April 2017||None[n 13]||10.3%||0|
|Alliance Party||Naomi Long||October 2016||None[n 14]||7.9%||0|
