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 Conservative and Unionist Party, commonly the Conservative Party and colloquially the Tories, is one of the two main political parties in the United Kingdom, along with the Labour Party. It sits on the centre-right to right-wing of the left–right political spectrum. Following its defeat by Labour at the 2024 general election it is currently the second-largest party by the number of votes cast and number of seats in the House of Commons; as such it has the formal parliamentary role of His Majesty's Most Loyal Opposition. It encompasses various ideological factions including one-nation conservatives, Thatcherites and traditionalist conservatives. There have been 20 Conservative prime ministers.

The Conservative Party was founded in 1834 from the Tory Party and was one of two dominant political parties in the 19th century, along with the Liberal Party. Under Benjamin Disraeli it played a preeminent role in politics at the height of the British Empire. In 1912 the Liberal Unionist Party merged with the party to form the Conservative and Unionist Party. Its rivalry with the Labour Party has shaped modern British politics for the last century. David Cameron sought to modernise the party after his election as leader in 2005, and the party governed from 2010 to 2024 under five prime ministers, latterly Rishi Sunak.

The Quint is an informal decision-making group consisting of the United States and the Big Four of Western Europe (France, Germany, Italy and the United Kingdom). All the countries forming it are allies and members of NATO, the OECD and the G7/G20.

The United States, France and the United Kingdom are nuclear-weapon states, while Germany and Italy are part of the nuclear weapons sharing program.

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.

The 2016 United Kingdom European Union membership referendum, commonly referred to as the EU referendum or the Brexit referendum, was a referendum that took place on 23 June 2016 in the United Kingdom (UK) and Gibraltar under the provisions of the European Union Referendum Act 2015 to ask the electorate whether the country should continue to remain a member of, or leave, the European Union (EU). The result was a vote in favour of leaving the EU, triggering calls to begin the process of the country's withdrawal from the EU commonly termed "Brexit".

Since 1973, the UK had been a member state of the EU and its predecessor the European Communities (principally the European Economic Community), along with other international bodies. The constitutional implications of membership for the UK became a topic of debate domestically particularly regarding sovereignty. A referendum on continued membership of the European Communities (EC) to try and settle the issue was held in 1975, with 67% of voters approving continued membership. Between 1975 and 2016 as European integration deepened, subsequent EC/EU treaties and agreements were ratified by the UK Parliament but without any public approval. Following the Conservative Party's victory at the 2015 general election as a main manifesto pledge, the legal basis for the EU referendum was established through the European Union Referendum Act 2015. Prime Minister David Cameron also oversaw a renegotiation of the terms of EU membership, intending to implement these changes in the event of a Remain result. The referendum was legally non-binding due to the ancient principle of parliamentary sovereignty, although the government promised to implement the result.

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.
