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 under the terms of the Constitution.

The executive branch of government is established in section 68 of the constitution, and it is vested in the monarch. The prime minister is appointed by the Governor-General. The prime minister must either be a member of the House and the leader of the political party with the support of the majority of the House's members; or the member of the House who, in the opinion of the Governor-General, is most likely to command the support of the majority of members of the House, if it appears to him that such party does not have an indisputable leader in the House or that no party commands the support of such a majority. Additionally, the nominee ought to be open to serving as prime minister.

Only the Prime Minister or, in his absence, the Minister the Prime Minister appoints in that regard, may call the Cabinet to order. Under section 73 of the constitution, the Governor General must revoke the appointment of the Prime Minister in the event that the House passes a resolution declaring its lack of confidence in the Prime Minister and the Prime Minister fails to resign from office or advise the Governor-General to dissolve Parliament within seven days of the resolution's passage. If parliament is dissolved, and a prime minister must be appointed, a person who was a member of the House immediately before the dissolution may be appointed as Prime Minister or any other Minister, and a person who was a member of the Senate immediately before the dissolution may be appointed as any Minister other than Prime Minister.

The Governor-General may authorize another member of the Cabinet to perform those functions (other than the functions conferred by section 74(2) of the constitution) when the Prime Minister is not present in Antigua and Barbuda or is unable to do so due to illness or because of the restrictions of section 73(4) of this Constitution. That member may perform those functions until the Governor-General revokes his authority.
