Leader of the Conservative Party (UK) in the context of "David Cameron"

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.

Alexander Boris de Pfeffel Johnson (born 19 June 1964) is a British politician and writer who served as Prime Minister of the United Kingdom and Leader of the Conservative Party from 2019 to 2022. He was previously Foreign Secretary from 2016 to 2018 and the second mayor of London from 2008 to 2016. He was Member of Parliament (MP) for Henley from 2001 to 2008 and for Uxbridge and South Ruislip from 2015 to 2023.

In his youth Johnson attended Eton College and Balliol College, Oxford, and he was elected president of the Oxford Union in 1986. In 1989 he began writing for The Daily Telegraph, and from 1999 to 2005 he was the editor of The Spectator. He became a member of the Shadow Cabinet of Michael Howard in 2001 before being dismissed over a claim that he had lied about an extramarital affair. After Howard resigned, Johnson became a member of David Cameron's Shadow Cabinet. He was elected mayor of London in 2008 and resigned from the House of Commons to focus his attention on the mayoralty. He was re-elected mayor in 2012, but did not run for re-election in 2016. At the 2015 general election he was elected MP for Uxbridge and South Ruislip. Johnson was a prominent figure in the Brexit campaign in the 2016 EU membership referendum. After the referendum, Prime Minister Theresa May appointed him foreign secretary. He resigned from the position in 2018 in protest at both the Chequers Agreement and May's approach to Brexit.

The 2005 United Kingdom general election was held on Thursday 5 May 2005, to elect 646 members to the House of Commons. The governing Labour Party led by Prime Minister Tony Blair won its third consecutive victory, with Blair becoming the second Labour leader after Harold Wilson to form three majority governments. However, its majority fell to 66 seats; the majority it won four years earlier had been of 167 seats. The UK media interpreted the results as an indicator of a breakdown in trust in the government, and especially in Blair.

This was the first time the Labour Party had won a third consecutive election, but would be the last election victory for Labour until 2024. The Liberal Democrats, led by Charles Kennedy, increased its seat count for a third consecutive election, netting the most seats in its history until 2024 and the most of any of the connected British Liberal parties since 1929. The Labour campaign emphasised a strong economy; however, Blair had suffered a decline in popularity, which was exacerbated by the controversial decision to send British troops to invade Iraq in 2003. Despite this, Labour mostly retained its leads over the Conservatives in opinion polls on economic competence and leadership, and Conservative leaders Iain Duncan Smith (2001–2003) and Michael Howard (2003–2005) struggled to capitalise on Blair's unpopularity, with the party consistently trailing behind Labour in the polls throughout the 2001–2005 parliament. The Conservatives campaigned on policies such as immigration limits, improving poorly managed hospitals, and reducing high crime rates. The Liberal Democrats took a strong stance against the Iraq War, particularly due to the absence of a second United Nations resolution; this anti-war position resonated with disenchanted Labour voters, leading to the Liberal Democrats achieving what was at that point their largest vote share in their history.

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.

Rishi Sunak (born 12 May 1980) is a British politician and former investment banker who served as Prime Minister of the United Kingdom and Leader of the Conservative Party from 2022 to 2024. Following his defeat to Keir Starmer's Labour Party in the 2024 general election, he became Leader of the Opposition, serving in this role from July to November 2024. He previously held two Cabinet positions under Boris Johnson, latterly as Chancellor of the Exchequer from 2020 to 2022. Sunak has been Member of Parliament (MP) for Richmond and Northallerton, previously Richmond (Yorks), since 2015.

Sunak was born in Southampton to parents of Indian descent who immigrated to Britain from East Africa in the 1960s. He was educated at Winchester College, studied philosophy, politics and economics at Lincoln College, Oxford, and earned a Master of Business Administration from Stanford University in California as a Fulbright Scholar. During his time at Oxford University, Sunak joined the Conservatives. After graduating, Sunak worked for Goldman Sachs and later as a partner at two hedge fund firms. Sunak was elected to the House of Commons at the 2015 general election. As a backbencher, Sunak supported the successful campaign for Brexit in the 2016 European Union membership referendum. Sunak was appointed to the junior ministerial position of Parliamentary Under-Secretary of State for Local Government by Theresa May in 2018, and was appointed to the cabinet-attending role of Chief Secretary to the Treasury by Johnson in 2019.

Witney is a county constituency in Oxfordshire represented in the House of Commons of the Parliament of the United Kingdom. It elects one Member of Parliament by the first-past-the-post system of election, and was created for the 1983 general election.

Historically a safe Conservative Party seat for the most part of its existence, it has been represented since 2024 by Charles Maynard of the Liberal Democrats. From 2001 to 2016, the constituency was represented by David Cameron, who was the prime minister from 2010 until his resignation in 2016, and the Leader of the Conservative Party (2005–2016).

Michael Howard, Baron Howard of Lympne CH PC KC (born Michael Hecht; 7 July 1941) is a British politician who was Leader of the Conservative Party and Leader of the Opposition from November 2003 to December 2005. He previously held cabinet positions in the governments of Margaret Thatcher and John Major, including Secretary of State for Employment, Secretary of State for the Environment and Home Secretary.

Howard was born in Swansea to a Jewish family, his father from Romania and his mother from Wales. He studied at Peterhouse, Cambridge, following which he joined the Young Conservatives. In 1964, he was called to the bar and became a Queen's Counsel in 1982. He first became a Member of Parliament at the 1983 general election, representing the constituency of Folkestone and Hythe. This quickly led to his promotion and Howard became Minister for Local Government in 1987. Under the premiership of John Major, he served as Secretary of State for Employment (1990–1992), Secretary of State for the Environment (1992–1993) and home secretary (1993–1997).

The 2005 Conservative Party leadership election was called by party leader Michael Howard on 6 May 2005, when he announced that he would be stepping down as Leader of the Conservative Party in the near future following the party's third successive general election defeat. However, he stated that he would not depart until a review of the rules for the leadership election had been conducted, given the high level of dissatisfaction with the current system. Ultimately, no changes were made and the election proceeded with the existing rules, which were introduced in 1998.

The contest formally began on 7 October 2005, when the Chairman of the 1922 Committee, Michael Spicer, received a letter of resignation from Howard. Nominations for candidates opened immediately, and closed on 13 October.

Margaret Hilda Thatcher, Baroness Thatcher (née Roberts; 13 October 1925 – 8 April 2013), was a British stateswoman who served as Prime Minister of the United Kingdom from 1979 to 1990 and Leader of the Conservative Party from 1975 to 1990. She was the longest-serving British prime minister of the 20th century and the first woman to hold the position. As prime minister, she implemented policies that came to be known as Thatcherism. A Soviet journalist dubbed her the "Iron Lady", a nickname that became associated with her uncompromising politics and leadership style.

Thatcher studied chemistry at Somerville College, Oxford, and worked briefly as a research chemist before becoming a barrister. She was elected Member of Parliament for Finchley in 1959. Edward Heath appointed her secretary of state for education and science in his 1970–1974 government. In 1975, she defeated Heath in the Conservative Party leadership election to become leader of the opposition, the first woman to lead a major political party in the UK.

The 2016 Conservative Party leadership election was held due to Prime Minister David Cameron's resignation as party leader. He had resigned after losing the national referendum to leave the European Union. Cameron, who supported Britain's continued membership of the EU, announced his resignation on 24 June, saying that he would step down by October. Theresa May won the contest on 11 July 2016, after the withdrawal of Andrea Leadsom left her as the sole candidate.

Conservative members of Parliament had voted initially in a series of ballots to determine which two candidates would go forward to a nationwide ballot of Conservative Party members for the final decision. Five Conservative MPs put themselves forward as candidates: Justice Secretary Michael Gove, Work and Pensions Secretary Stephen Crabb, former Defence Secretary Liam Fox, Minister of State for Energy and Climate Change Andrea Leadsom, and Home Secretary Theresa May. Former Mayor of London Boris Johnson, seen as the front runner by political analysts, surprised many commentators by choosing not to run after Gove withdrew his backing and announced his own candidacy.

David Cameron was Leader of the Conservative Party and Leader of the Opposition from his election as Leader on 6 December 2005 until he became Prime Minister on 11 May 2010. His tenure as opposition leader was characterised by opposition to the Great Recession from 2007 to 2009, and his relative youth and inexperience before becoming leader invited satirical comparison with Tony Blair. Cameron sought to rebrand the Conservatives, embracing an increasingly socially liberal position, and introducing the "A-List" to increase the number of female and minority ethnic Conservative MPs.

Cameron had four Shadow Cabinets during his tenure as opposition leader. His Shadow Cabinet appointments included MPs associated with the various wings of the party. Former leader William Hague was appointed to the Foreign Affairs brief, while both George Osborne and David Davis were retained, as Shadow Chancellor of the Exchequer and Shadow Home Secretary respectively. Hague, assisted by Davis, stood in for Cameron during his paternity leave in February 2006. In June 2008, Davis announced his intention to resign as an MP, and was immediately replaced as Shadow Home Secretary by Dominic Grieve; Davis' surprise move was seen as a challenge to the changes introduced under Cameron's leadership.

Stanley Baldwin, 1st Earl Baldwin of Bewdley (3 August 1867 – 14 December 1947), was a British statesman and Conservative politician who was prominent in the political leadership of the United Kingdom between the world wars. He was prime minister on three occasions, from May 1923 to January 1924, from November 1924 to June 1929 and from June 1935 to May 1937.

Born to a prosperous family in Bewdley, Worcestershire, Baldwin was educated at Hawtreys, Harrow School and Trinity College, Cambridge. He joined the family iron- and steel-making business and entered the House of Commons in 1908 as the member for Bewdley, succeeding his father Alfred. He was Financial Secretary to the Treasury (1917–1921) and President of the Board of Trade (1921–1922) in the coalition ministry of David Lloyd George and then rose rapidly. In 1922, Baldwin was one of the prime movers in the withdrawal of Conservative support from Lloyd George; he subsequently became Chancellor of the Exchequer in Bonar Law's Conservative ministry. Upon Law's resignation for health reasons in May 1923, Baldwin became prime minister and leader of the Conservative Party. He called an election in December 1923 on the issue of tariffs and lost the Conservatives' parliamentary majority, after which Ramsay MacDonald formed a minority Labour government.

David Cameron formed the second Cameron ministry, the first Conservative majority government since 1996, following the 2015 general election. Prior to the election Cameron had led his first ministry, the Cameron–Clegg coalition, a coalition government that consisted of members of the Conservatives and the Liberal Democrats, with Liberal Democrat leader Nick Clegg as deputy prime minister.

Following the vote to leave at the EU referendum on the morning of 24 June, Cameron said that he would resign as prime minister after a new Leader of the Conservative Party was chosen after the party conference in the autumn. It was announced on 11 July 2016 that he would resign on 13 July and be succeeded by Home Secretary, Theresa May.

Mary Elizabeth Truss (born 26 July 1975) is a British politician who was Prime Minister of the United Kingdom and Leader of the Conservative Party from September to October 2022. On her fiftieth day in office, she stepped down amid a government crisis, making her the shortest-serving prime minister in British history. The member of Parliament (MP) for South West Norfolk from 2010 to 2024, Truss held various Cabinet positions under three prime ministers—David Cameron, Theresa May and Boris Johnson—lastly as foreign secretary from 2021 to 2022.

Truss studied philosophy, politics and economics at Merton College, Oxford, and was the president of the Oxford University Liberal Democrats. In 1996, she joined the Conservative Party. She worked at Royal Dutch Shell and Cable & Wireless and was the deputy director of the think tank Reform. After two unsuccessful attempts to be elected to the House of Commons, she became the MP for South West Norfolk at the 2010 general election. As a backbencher, she called for reform in several policy areas including the economy, childcare and mathematics in education. Truss co-founded the Free Enterprise Group of Conservative MPs and wrote or co-wrote a number of papers and books, including After the Coalition and Britannia Unchained.

The Sunak ministry began on 25 October 2022 when Rishi Sunak was invited by King Charles III to succeed Liz Truss as Prime Minister of the United Kingdom. The previous day, Sunak had been elected unopposed as leader of the Conservative Party following Truss's resignation. The Sunak ministry was formed from the 2019 Parliament of the United Kingdom, as a Conservative majority government. Sunak reshuffled his cabinet twice, first in February 2023 and later in November 2023.

On 22 May 2024, Sunak announced a general election on 4 July, in which the Labour Party won a landslide victory, leading to the formations of the Starmer ministry and the Sunak shadow cabinet.

Sir George Iain Duncan Smith (born 9 April 1954), often referred to by his initials IDS, is a British politician who was Leader of the Conservative Party and Leader of the Opposition from 2001 to 2003. He was Secretary of State for Work and Pensions from 2010 to 2016. He has been Member of Parliament (MP) for Chingford and Woodford Green, formerly Chingford, since 1992.

The son of W. G. G. Duncan Smith, a Royal Air Force flying-ace, Duncan Smith was born in Edinburgh and raised in Solihull. After education at the HMS Conway training school and the Royal Military Academy Sandhurst, he served in the Scots Guards from 1975 to 1981, seeing tours in Northern Ireland and in Rhodesia. He joined the Conservative Party in 1981. After unsuccessfully contesting Bradford West in 1987, he was elected to Parliament at the 1992 general election. He was a backbencher during the premiership of John Major (in office from 1990 to 1997). In the shadow cabinet of William Hague, Duncan Smith served as Shadow Secretary of State for Social Security between 1997 and 1998, and as Shadow Secretary of State for Defence from 1998 to 2001.

The 2019 United Kingdom general election was held on Thursday 12 December 2019, with 47,074,800 registered voters entitled to vote to elect 650 Members of Parliament (MPs) to the House of Commons. The governing Conservative Party, led by Prime Minister Boris Johnson, won a landslide victory with a majority of 80 seats, a net gain of 48, on 43.6 per cent of the popular vote, the highest percentage for any party since the 1979 general election, though with a narrower popular vote margin than that achieved by the Labour Party over the Conservatives at the 1997 general election. This was the second national election to be held in 2019 in the United Kingdom, the first being the 2019 European Parliament election.

After it lost its parliamentary majority at the 2017 general election, the Conservative Party governed in minority with the support of the Democratic Unionist Party (DUP). The prime minister, Theresa May, resigned in July 2019 after repeatedly failing to pass her Brexit withdrawal agreement in parliament. Johnson succeeded her as the leader of the Conservative Party and as prime minister in July 2019. Johnson could not persuade Parliament to approve a revised withdrawal agreement by the end of October, and chose to call a snap election, which the House of Commons supported under the Early Parliamentary General Election Act 2019. Opinion polls showed a firm lead for the Conservatives against the opposition Labour Party throughout the campaign.
