Part of the Leeward Islands colony, Antigua and Barbuda became part of the short-lived West Indies Federation from 1958 to 1962. Antigua and Barbuda subsequently became an associated state of the United Kingdom with full internal autonomy on 27 February 1967. The 1970s were dominated by discussions as to the islands' future and the rivalry between Vere Bird of the Antigua Labour Party (ALP) (Premier from 1967 to 1971 and 1976 to 1981) and the Progressive Labour Movement (PLM) of George Walter (Premier 1971–1976). Eventually Antigua and Barbuda gained full independence on 1 November 1981; Vere Bird became Prime Minister of the new country. The country opted to remain within the Commonwealth, retaining Queen Elizabeth as head of state, with the last Governor, Sir Wilfred Jacobs, as Governor-General.
