Labour government, 1974–1979
In March 1976, having just turned sixty years old, Wilson resigned as Prime Minister, ending his leadership of the Labour Party after thirteen years, and a total of nearly eight years as Prime Minister. He was replaced by James Callaghan, who had held senior government positions during both of Wilson's ministries, and had served as a Shadow Cabinet member in the early-1960s.
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.
