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.
John P. Wilson
In 1990 Wilson challenged Brian Lenihan for the Fianna Fáil nomination for the 1990 presidential election. Lenihan won the nomination but failed to be elected President and was also sacked from the government. Wilson was then appointed Tánaiste. He remained in the cabinet until retirement in 1993. Although the 26th Dail was dissolved in December 1992, Wilson served in Government until the new government took office.
