Commissioner for the British Indian Ocean Territory

The Commissioner for the British Indian Ocean Territory is the head of government in the United Kingdom's overseas territory of the British Indian Ocean Territory. The Commissioner was appointed by the British monarch on the advice of the Foreign and Commonwealth Office. The Commissioner did not reside in the territory, as it has had no native population since the forced depopulation of the Chagossian people in the 1970s, and the only population is the military of the United States and the United Kingdom at the joint base at Diego Garcia.

The Commissioner's role was to administer the territory on behalf of the British government. This involves the passing of any necessary legislation for the territory, usually Orders in Council or Statutory Instruments. The Commissioner is also responsible for liaising with the military of the United States in matters concerning the territory. An Administrator for the British Indian Ocean Territory acts as the Commissioner's assistant. The Commissioner also appoints a representative on the territory, who is the senior British military officer at Diego Garcia.
