The 2019 United Kingdom general election was held on Thursday 12 December 2019 with 47,074,800 registered voters entitled to vote to elect members of the House of Commons. The Conservative Party won a landslide victory with a majority of 80 seats, a net gain of 48, on 43.6% of the popular vote, the highest percentage for any party since the 1979 general election, though with a narrower popular vote margin than that achieved by Labour over the Conservatives in 1997.

The Conservative and Unionist Party, commonly the Conservative Party and colloquially known as the Tories, is one of the two main political parties in the United Kingdom, along with the Labour Party. It is the current governing party, having won the 2019 general election, and has been the primary governing party in the United Kingdom since 2010. The party sits on the right-wing to centre-right of the political spectrum. It encompasses various ideological factions including one-nation conservatives, Thatcherites, and traditionalist conservatives. The party holds the annual Conservative Party Conference, at which senior Conservative figures promote party policy.
