Alec Douglas-Home, British cricketer and politician, Prime Minister of the United Kingdom (born 1903)

Alexander Frederick Douglas-Home, Baron Home of the Hirsel, known as Lord Dunglass from 1918 to 1951 and the Earl of Home from 1951 to 1963, was a British statesman and Conservative politician who served as Prime Minister of the United Kingdom from 1963 to 1964. He was 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 prime minister of the United Kingdom is the head of government of the United Kingdom. The prime minister advises the sovereign on the exercise of much of the royal prerogative, chairs the Cabinet, and selects its ministers. Modern prime ministers hold office by virtue of their ability to command the confidence of the House of Commons, so they are invariably members of Parliament.
