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.
Gordon Wilson (Scottish politician)
Wilson joined the Scottish National Party in 1959, on his graduation from university. He was "controller" of the political pirate radio station Radio Free Scotland, which broadcast on a frequency used by BBC between 1956 and 1965, moving the location of the transmitter to avoid being caught. Wilson served as Assistant National Secretary of the SNP from 1963 to 1964, as National Secretary from 1964 to 1971, and was vice-chairman of the SNP Oil Campaign Committee, which was responsible for the party's iconic It's Scotland's oil campaign. It was Wilson who coined the slogan.
