Politics of Saint Helena takes place in a framework of limited self-government as a dependent territory of the United Kingdom, whereby the governor is the head of government. Saint Helena, an island in the southern Atlantic Ocean, is a part of the British overseas territory of Saint Helena, Ascension and Tristan da Cunha. It has had its present constitution since 1 September 2009. Executive power is exercised by the governor and the Executive Council. Legislative power is vested in both the governor and the Legislative Council. The judiciary is independent of the executive and the legislature.
