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.
Frank Cousins
Cousins played a significant role in helping Harold Wilson become leader of the Labour Party and served in Wilson's cabinet as Minister of Technology from October 1964 until his resignation on 11 June 1966 to protest against a Government-backed law freezing incomes and prices. His appointment as a Minister was notable as he is only one of two recent Ministers (the other being Patrick Gordon-Walker) who was appointed to the role without being either a Member of Parliament or a member of the House of Lords. He was also made a Privy Counsellor in 1964.
