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.

In addition to the damage done to its reputation by devaluation, Wilson's Government suffered from the perception that its response to industrial relations problems was inadequate. A six-week strike of members of the National Union of Seamen, which began shortly after Wilson' re-election in 1966, did much to reinforce this perception, along with Wilson's own sense of insecurity in office.
