Prime Minister of Antigua and Barbuda

The prime minister of Antigua and Barbuda is the head of government of the Antigua and Barbuda. The prime minister of Antigua and Barbuda is appointed by the Governor-General. The prime minister chairs the Cabinet, selects its ministers, and exercises much of the executive powers afforded to the office under the Constitution. The prime minister holds office by virtue of their ability to command the confidence of the House of Representatives, of which they must be an elected member of.

The power of the prime minister has fluctuated throughout the position's existence. While the Governor-General has been described as the de facto head of state, in whom all executive power is vested in, the prime minister has always been the head of government and has exercised his powers similar in fashion to an executive president in most liberal democracies. The prime minister, along with Cabinet, is responsible for proposing new legislation and setting an agenda, usually codified by acts of parliament or statutory instruments.

The history of such an office began in 1872 with the colonial president, who oversaw the island in subordination to the island's governor. This office was later superseded by the positions of administrator, chief minister, and premier, each of which gaining more executive power as the islands moved toward independence. Four men have served as prime minister, the first being Vere Bird taking office on 1 November 1981. The longest serving prime minister was also Vere Bird, who served for 12 years, and the shortest serving was his son Lester, who served for ten years. Gaston Browne succeeded Baldwin Spencer as prime minister on 13 June 2014, following the 2014 general election.
