2010 United Kingdom general election in the context of "Conservative Party (UK)"

The Parliament of the United Kingdom currently has 650 parliamentary constituencies across the constituent countries (England, Scotland, Wales, and Northern Ireland), each electing a single member of parliament (MP) to the House of Commons by the plurality (first-past-the-post) voting system, ordinarily every five years. Voting last took place in all 650 of those constituencies at the United Kingdom general election on 4 July 2024.

The number of seats rose from 646 to 650 at the 2010 general election after proposals made by the boundary commissions for England, Wales, and Northern Ireland (the Fifth Periodic Review of Westminster constituencies) were adopted through statutory instruments. Constituencies in Scotland remained unchanged, as the Boundary Commission for Scotland had completed a review just before the 2005 general election, which had resulted in a reduction of 13 seats.

David William Donald Cameron, Baron Cameron of Chipping Norton (born 9 October 1966), is a British politician who served as Prime Minister of the United Kingdom from 2010 to 2016. Until 2015, he led the first coalition government in the UK since 1945 and resigned after a referendum supported the country's leaving the European Union. After his premiership, he served as Foreign Secretary in the government of prime minister Rishi Sunak from 2023 to 2024. Cameron was Leader of the Conservative Party from 2005 to 2016 and served as Leader of the Opposition from 2005 to 2010. He was Member of Parliament (MP) for Witney from 2001 to 2016, and has been a member of the House of Lords since November 2023. Cameron identifies as a one-nation conservative and has been associated with both economically liberal and socially liberal policies.

Born in London to an upper-middle-class family, Cameron was educated at Eton College and Brasenose College, Oxford. After becoming an MP in 2001, he served in the opposition Shadow Cabinet under Conservative leader Michael Howard, and succeeded Howard in 2005. Following the 2010 general election, negotiations led to Cameron becoming prime minister as the head of a coalition government with the Liberal Democrats.

Theresa Mary May, Baroness May of Maidenhead (/təˈriːzə/; née Brasier; born 1 October 1956), is a British politician who served as Prime Minister of the United Kingdom and Leader of the Conservative Party from 2016 to 2019. She previously served as Home Secretary from 2010 to 2016. She was Member of Parliament (MP) for Maidenhead from 1997 to 2024, and has been a member of the House of Lords since August 2024. May was the second female British prime minister, after Margaret Thatcher, and the first woman to have held two of the Great Offices of State. May is a one-nation conservative.

May grew up in Oxfordshire and attended St Hugh's College, Oxford. After graduating in 1977, she worked at the Bank of England and the Association for Payment Clearing Services. She also served as a councillor on Merton London Borough Council. After two unsuccessful attempts to be elected to the House of Commons, she was elected MP for Maidenhead at the 1997 general election. From 1999 to 2010, May held several roles in shadow cabinets and was Chairman of the Conservative Party from 2002 to 2003. Following the formation of the coalition government after the 2010 general election, May was appointed home secretary and minister for women and equalities, giving up the latter role in 2012. Reappointed after the Conservatives won the 2015 general election, she became the longest-serving home secretary in more than 60 years. During her tenure as home secretary, she pursued reform of the Police Federation, implemented a harder line on drugs policy and further restricted immigration. She oversaw the introduction of elected police and crime commissioners, the deportation of Abu Qatada and the creation of the College of Policing and the National Crime Agency. Although she supported the Remain campaign, May supported Brexit following the outcome of the 2016 referendum. She was elected and appointed prime minister unopposed, succeeding David Cameron.

The fifth periodic review of Westminster constituencies was undertaken between 2000 and 2007 by the four boundary commissions for England, Scotland, Wales and Northern Ireland for the UK Parliament. The changes for England, Wales and Northern Ireland took effect at the 2010 general election; that for Scotland took effect at the 2005 election. Changes were also made to the constituencies and electoral regions of the then National Assembly for Wales (now the Senedd), and took effect at the 2007 Assembly election. All of the recommendations were approved.

The 2017 United Kingdom general election was held on Thursday 8 June 2017, two years after the previous general election in 2015; it was the first since 1992 to be held on a day that did not coincide with any local elections. The governing Conservative Party led by Prime Minister Theresa May remained the largest single party in the House of Commons but lost its small overall majority, resulting in the formation of a Conservative minority government with a confidence and supply agreement with the Democratic Unionist Party (DUP) of Northern Ireland.

The Conservative Party, which had governed as a senior coalition partner from 2010 and as a single-party majority government from 2015, was led by May as Prime Minister. It was defending a working majority of 17 seats against the opposition Labour Party led by Jeremy Corbyn. It was the first general election to be contested by either May or Corbyn as party leader; May had succeeded David Cameron following his resignation as prime minister the previous summer, while Corbyn had succeeded Ed Miliband after he resigned following Labour's failure to win the general election two years earlier.

David Cameron's tenure as Prime Minister of the United Kingdom began on 11 May 2010 when he accepted an invitation of Queen Elizabeth II to form a government, succeeding Gordon Brown of the Labour Party, and ended on 13 July 2016 upon his resignation following the 2016 referendum that favoured Brexit, which he had opposed. As prime minister, Cameron also served simultaneously as First Lord of the Treasury, Minister for the Civil Service, and Leader of the Conservative Party.

Following the 2010 general election, Cameron became prime minister at the head of a coalition government between the Conservatives and Liberal Democrats, as no party had gained an overall majority in the House of Commons for the first time since the February 1974 general election. He appointed Nick Clegg, Leader of the Liberal Democrats, Deputy Prime Minister. Between them, the Conservatives and Liberal Democrats controlled 363 seats in the House of Commons, with a majority of 76 seats.

The events surrounding the formation of the United Kingdom's government in 2010 took place between 7 May and 12 May 2010, following the 2010 general election, which failed to produce an overall majority for either of the country's two main political parties. The election, held on 6 May, resulted in the first hung parliament in the UK in 36 years, sparking a series of negotiations which would form the first coalition government since the Second World War.

The governing Labour administration led by Gordon Brown was defeated in the election and lost its overall majority after 13 years in office, but continued in office in an acting capacity until a government could be formed. The opposition Conservative Party led by David Cameron, won the largest number of seats in the new Parliament, but fell short of the number required to secure an overall majority. Consequently, senior figures from both parties embarked on a series of meetings with representatives from the Liberal Democrats led by Nick Clegg, aimed at forming a coalition government.

The Cameron–Clegg coalition was formed by David Cameron and Nick Clegg when Cameron was invited by Queen Elizabeth II to form a new government, following the resignation of Prime Minister Gordon Brown on 11 May 2010, after the general election on 6 May. It was the UK's first coalition government since the Churchill war ministry ended in 1945.

The coalition was led by Cameron as prime minister with Clegg as deputy prime minister and composed of members of both Cameron's centre-right Conservative Party and Clegg's centrist Liberal Democrats. The Cabinet was made up of sixteen Conservatives and five Liberal Democrats, with eight other Conservatives and one other Liberal Democrat attending cabinet but not members. The coalition was succeeded by the single-party, second Cameron ministry following the 2015 election.

The 2015 United Kingdom general election was held on Thursday, 7 May 2015 to elect 650 members of Parliament (MPs) to the House of Commons. The Conservative Party, led by Prime Minister David Cameron, won an unexpected majority victory of ten seats; they had been leading a coalition government with the Liberal Democrats. It was the last general election to be held before the UK voted to leave the European Union (EU) in June 2016.

Opinion polls and political commentators had widely predicted that the election would result in a second consecutive hung parliament whose composition would be similar to the one elected at the previous general election in 2010. Potential coalitions and agreements between parties were intensively discussed; as a result, smaller parties received much more attention during the campaign than in previous UK elections. However, opinion polls underestimated the Conservatives, as they won 330 of the 650 seats and 36.9 per cent of the vote, giving them a small overall majority.
