In the United Kingdom's 2017 general election, 650 Members of Parliament (MPs) were elected to the House of Commons – one for each parliamentary constituency. A record number of women (208) were elected as MPs.^[1]

Parliament consists of the House of Lords and the elected House of Commons.^[2] The State Opening of Parliament at the Palace of Westminster by Queen Elizabeth II was on 21 June 2017. The subsequent parliamentary session was the longest since the formation of the United Kingdom in 1707, and the longest to sit at Westminster since the Long Parliament in the 17th century.^[3] The second and last parliamentary session however was the shortest since October 1948,^[4] lasting less than a month, from 14 October 2019 until Parliament dissolved at 00:01 on 6 November 2019.^[5]

Notable newcomers to enter the House of Commons in this General Election included future Secretary of State for Scotland Alister Jack and future Scottish Conservative leader Douglas Ross. For the opposition, newcomers included Shadow Chancellor of the Exchequer Anneliese Dodds and future Shadow Secretary of State for Women and Equalities Marsha de Cordova.

The Parliament was marked by extraordinary political turmoil as Governments led by Theresa May and Boris Johnson were unable to win a series of important votes on the issue of Brexit. This left both Parliament and the Government in a prolonged state of deadlock and unable to move forward on the issue. Consequently, there was an unusually high number of defections and suspensions, including the suspension of 21 Conservative MPs in September 2019; 10 of those suspended MPs re-joined the Conservative Party in October 2019. The Parliament was dissolved after MPs passed the Early Parliamentary General Election Act 2019, which bypassed the Fixed-term Parliaments Act 2011 to bring the next election forward to December 2019 from its original scheduled May 2022 date.
