Alexander Frederick Douglas-Home, Baron Home of the Hirsel,, styled as Lord Dunglass between 1918 and 1951 and the Earl of Home from 1951 until 1963, was a British statesman and Conservative politician who served as Prime Minister of the United Kingdom from 1963 to 1964. He is notable for being the last prime minister to hold office while being a member of the House of Lords, before renouncing his peerage and taking up a seat in the House of Commons for the remainder of his premiership. His reputation, however, rests more on his two stints as Foreign Secretary than on his brief premiership.

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.
