Edward Gough Whitlam was the 21st prime minister of Australia, serving from 1972 to 1975. He held office as the leader of the Australian Labor Party (ALP), of which he was the longest-serving. He was notable for being the head of a reformist and socially progressive administration that ended with his removal as prime minister after controversially being dismissed by the governor-general of Australia, Sir John Kerr, at the climax of the 1975 constitutional crisis. Whitlam is the only Australian prime minister to have been removed from office by the governor-general.
