The politics of Gibraltar takes place within a framework of a parliamentary representative democratic British Overseas Territory, whereby the Monarch of the United Kingdom is the constitutional head of state represented by the Governor of Gibraltar. The Chief Minister of Gibraltar is the head of Government. As a British Overseas Territory, the Government of Gibraltar is not subordinate to the Government of the United Kingdom. The British Government, however, is responsible for defence and external affairs but Gibraltar has full internal self-government under its 2006 Constitution.
