United KingdomTheresa Mary May MP (born 1 October 1956) is a British politician serving as Prime Minister of the United Kingdom since 2016. She served as Home Secretary from 2010 to 2016, and served as Leader of the Conservative Party from 2016 to 2019. May was first elected Member of Parliament (MP) for Maidenhead in 1997. Ideologically, she identifies herself as a one-nation conservative.
In the 1992 general election May stood unsuccessfully for the safe Labour seat of North West Durham, placing second to incumbent MP Hilary Armstrong by 12,747 votes (27.6%) to 26,734 (57.8%), with future Liberal Democrat leader Tim Farron placing third.
Ahead of the 1997 general election, May was selected as the Conservative candidate for Maidenhead, a new seat which was created from parts of the seats of Windsor and Maidenhead and Wokingham. She was elected with 25,344 votes (49.8%), almost double the total of second-placed Andrew Terence Ketteringham of the Liberal Democrats, who took 13,363 votes (26.3%).
On 6 May 2010, May was re-elected MP for Maidenhead with an increased majority of 16,769 – 60% of the vote. This followed an earlier failed attempt by the Liberal Democrats to unseat her in 2005, as one of that party's leading "decapitation-strategy" targets.
On 12 May 2010, when May was appointed Home Secretary and Minister for Women and Equality by Prime Minister David Cameron as part of his first Cabinet, she became the fourth woman to hold one of the British Great Offices of State, after Margaret Thatcher (Prime Minister), Margaret Beckett (Foreign Secretary) and Jacqui Smith (Home Secretary).
On 30 June 2016, May announced her candidacy for the leadership of the Conservative Party to replace David Cameron, who resigned following the outcome of the European Union membership referendum in which 52% of voters voted in favour of leaving the EU.
On 15 January 2019, May's government was defeated in the House of Commons by a margin of 230 votes (202 in favour and 432 opposed) in a vote on her deal to leave the European Union. It was the largest majority against a United Kingdom government in history.
