Ascension Island is part of the United Kingdom Overseas Territory of St Helena, Ascension, and Tristan da Cunha. The territory is presided over by a Governor who is resident on St Helena and appointed by HM the Queen. The Governor is represented on Ascension by the Administrator. A revised Constitution entered into force in September 2009. An elected Island Council advises the Governor on laws, policies and the government’s annual budget.
Ascension, like other Overseas Territories and the Crown Territories, is not part of the United Kingdom. It has its own Constitution (shared with St Helena and Tristan da Cunha), is internally self-governing, makes its own laws, has a separate fiscal jurisdiction and has tax raising powers through the Governor. The United Kingdom is responsible for the defence, international relations, and internal security of the territory.
Unlike most places however there is no indigenous or permanent population. The inhabitants of the island comprise the employees of the organisations operating on the island and their families.
