Conservative Party

The Conservative and Unionist Party, commonly the Conservative Party and colloquially the Tories, is a political party in the United Kingdom. It sits on the centre-right to right-wing of the left–right political spectrum. Following its defeat by Labour Party at the 2024 general election, it is currently the second-largest party by the number of votes cast and number of seats in the House of Commons; as such it has the formal parliamentary role of His Majesty's Most Loyal Opposition. It encompasses various ideological factions including one-nation conservatives, Thatcherites and traditionalist conservatives. There have been 20 Conservative prime ministers. The party meets annually during autumn, for the Conservative Party Conference.

The Conservative Party was founded in 1834 from the Tory Party and was one of two dominant political parties in the 19th century, along with the Liberal Party. Under Benjamin Disraeli it played a preeminent role in politics at the height of the British Empire. In 1912, the Liberal Unionist Party merged with the party to form the Conservative and Unionist Party. Its rivalry with the Labour Party has shaped modern British politics for the last century. David Cameron sought to modernise the party after his election as leader in 2005, and the party governed from 2010 to 2024 under five prime ministers, latterly Rishi Sunak.
