Harold Wilson
James Harold Wilson, Baron Wilson of Rievaulx, (11 March 1916– 24 May 1995) was a British Labour politician who served as Prime Minister of the United Kingdom from 1964 to 1970 and 1974 to 1976.
History of the Conservative Party (UK)
The party at this time lacked a formal process for electing a new leader and Macmillan's resignation took place in the week of the annual Conservative Party Conference. This event rapidly became an American-style convention as leading ministers sought to establish their credentials. Eventually Macmillan formally recommended to the Queen that she appoint the Earl of Home as Prime Minister. Home was appointed and renounced his peerage, becoming Sir Alec Douglas-Home, but was unable to restore the party's fortunes and narrowly lost the 1964 general election to Harold Wilson's Labour, who ended 13 years of Conservative rule.
