The United Kingdom general election of 2017 took place on 8 June 2017. Each of the 650 parliamentary constituencies elected one Member of Parliament (MP) to the House of Commons, the lower house of Parliament. In line with the Fixed-term Parliaments Act 2011, an election had not been due until 7 May 2020, but a call by Prime Minister Theresa May for a snap election received the necessary two-thirds majority in a 522-to-13 vote in the House of Commons on 19 April 2017.
The Conservative Party, which has governed since 2015 (and as a senior coalition partner from 2010), was defending a majority of 12 against the Labour Party, the official opposition. Theresa May had hoped to get a larger majority for the Conservatives to “strengthen [her] hand in the Brexit negotiations”. Some of the opinion polls had shown a twenty-point lead over Labour led by Jeremy Corbyn before the election was called, but this lead had narrowed by the time of the election. Contrarily to May’s intentions, the Conservative Party lost its parliamentary majority as the election resulted in a hung parliament. Following the result, the Conservatives entered into talks with the right-wing Democratic Unionist Party (DUP) of Northern Ireland, whose additional 10 seats could allow for the formation of a Tory-DUP coalition government.
