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.[2] [3]
The Constitution of Antigua and Barbuda regulates that the prime minister must be a member of the House of Representatives who is the leader in the House of the political party that has the support of the majority of members of the House of Representatives. If there is no party that has an undisputed leader, or no party that maintains the support of the majority of the House of Representatives, the Governor-General may appoint a member that is most likely to maintain the support of the majority of the members, and who is willing to hold the role of prime minister.If a prime minister must be appointed while Parliament is dissolved, then, a person who was a member of the House of Representatives immediately before the dissolution may be appointed as 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.
The prime minister advises the Governor-General on appointments to the Cabinet of Antigua and Barbuda. 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 dismiss the Prime Minister or dissolve parliament in the event of a successful vote of no confidence.
