Theresa May in the context of "Home Secretary"

The Brexit withdrawal agreement, officially titled Agreement on the withdrawal of the United Kingdom of Great Britain and Northern Ireland from the European Union and the European Atomic Energy Community, is a treaty between the European Union (EU), Euratom, and the United Kingdom (UK), signed on 24 January 2020, setting the terms of the withdrawal of the UK from the EU and Euratom. The text of the treaty was published on 17 October 2019, and is a renegotiated version of an agreement published in November 2018. The earlier version of the withdrawal agreement was rejected by the House of Commons on three occasions, leading to the resignation of Theresa May as Prime Minister and the appointment of Boris Johnson as the new prime minister on 24 July 2019.

The Parliament of the United Kingdom gave its approval to the agreement on 23 January 2020 and the UK government deposited Britain's instrument of ratification on 29 January 2020. The agreement was ratified by the Council of the European Union on 30 January 2020, following the consent of the European Parliament on 29 January 2020. The United Kingdom's withdrawal from the Union took effect on 11 p.m. GMT on 31 January 2020, and at that moment the Withdrawal Agreement entered into force, as per its article 185.

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 European Union (Notification of Withdrawal) Act 2017 (c. 9) was an Act of the Parliament of the United Kingdom to empower the Prime Minister to give to the Council of the European Union the formal notice – required by Article 50 of the Treaty on European Union – for starting negotiations for the United Kingdom's withdrawal from the European Union. It was passed following the result of the 2016 United Kingdom European Union membership referendum held on 23 June in which 51.9% of voters voted to leave the European Union.

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.

On 29 March 2017, the United Kingdom (UK) invoked Article 50 of the Treaty on European Union which began the member state's withdrawal, commonly known as Brexit, from the European Union (EU). In compliance with the treaty, the UK gave formal notice to the European Council of its intention to withdraw from the EU to allow withdrawal negotiations to begin.

The process of leaving the EU was begun after a referendum held in June 2016 at which 52% of the votes were in favour of UK withdrawal. In October 2016, the UK prime minister, Theresa May, announced that Article 50 would be invoked by "the first quarter of 2017". On 24 January 2017 the Supreme Court ruled in Miller I that the process could not be initiated without an authorising Act of Parliament, and unanimously ruled against the Scottish Government's claim in respect of devolution. Consequently, the European Union (Notification of Withdrawal) Act 2017 empowering the prime minister to invoke Article 50 was enacted in March 2017.

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.

Maidenhead is a constituency in Berkshire represented in the House of Commons of the Parliament of the United Kingdom by Joshua Reynolds, a Liberal Democrat, since 2024. Following its creation at the 1997 general election, the seat was held for twenty-seven years by Conservative Member of Parliament Theresa May, who served as Home Secretary from 2010 to 2016 and as Prime Minister from 2016 to 2019.

Prior to the 2024 general election, it was considered a safe seat for the Conservative Party.
