The governor-general was the representative of the monarch in the Gambia and exercised most of the powers of the monarch. The governor-general was appointed for an indefinite term, serving at the pleasure of the monarch. Since the Gambia was granted independence by the Gambia Independence Act 1964, rather than being first established as a semi-autonomous dominion and later promoted to independence as defined by the Statute of Westminster 1931, the governor-general was to be always appointed solely on the advice of the Cabinet of the Gambia without the involvement of the British government, with the sole exception of John Paul, the former colonial governor, who served as governor-general temporarily until he was replaced by Farimang Mamadi Singateh. In the event of a vacancy the chief justice would have served as the officer administering the government.
Under the Constitution of 1970, the first constitution of the Republic of the Gambia, the president replaced the monarch as executive head of state. The president was elected by the National Assembly for a five-year term. In the event of a vacancy the vice-president served as acting president.
Under the current constitution of the Republic of The Gambia, the president is executive head of state. The president is elected by popular vote for a five-year term. In the event of a vacancy, the vice-president will serve as acting president.
