About the election

Prime Minister Boris Johnson’s Conservative Party regained the majority in early elections, the third general elections held in less than five years. It increased its share from 317 to 365 seats in the 650-member House of Commons. On the other hand, the Labour Party, led by Mr. Jeremy Corbyn, reduced its share of seats from 265 to 202. The Scottish National Party, led by Ms. Nicola Sturgeon, took a record 47 seats, up from 35. Liberal Democrat leader Jo Swinson lost her seat. A record 220 women were elected, up from 208 in 2017: Both the Labour Party and the Liberal Democrats have more women MPs than men.

The 2019 snap elections followed parliamentary deadlock over Brexit (see note), which worsened after the 2017 snap elections when the Conservative Party lost its majority. Amid mounting criticism over the handling of Brexit, Prime Minister Theresa May (Conservative) resigned and was succeeded by Mr. Johnson in July 2019. He initially announced that the United Kingdom would leave the European Union (EU) by 31 October 2019 with or without a deal but the Government requested a new three-month extension from the EU in October. Following the ensuing parliamentary deadlock, the new Prime Minister called snap elections for 12 December. During the election campaign, the Conservative Party promised that it would leave the EU by 31 January 2020. The Labour Party promised to renegotiate Brexit and call a second referendum on the new deal. The Scottish National Party said it would support a second referendum, adding that Scotland would join the EU if it became independent. The Liberal Democrats pledged to cancel Brexit altogether.


A referendum on Brexit (from a merging of the words "Britain" and "exit") to decide whether the United Kingdom should leave or remain in the European Union was held in June 2016. Leave camps narrowly won the referendum. Brexit was initially due to happen on 29 March 2019, but the deadline was extended twice after Parliament rejected the deal negotiated by the then Prime Minister, Theresa May. Following the December 2019 elections, the United Kingdom left the EU on 31 January 2020.
