Saint Lucia is a unitary state with a parliamentary system. It is a Commonwealth realm and a constitutional monarchy, with the current monarch being Charles III, who is represented on the island by a governor-general, currently Errol Charles. The prime minister (currently Philip J. Pierre) is the head of government, the head of the cabinet, and is normally the leader of the largest party in the House of Assembly. The house has 17 seats, with each member being elected via a plurality of votes in their constituency. The upper chamber of Parliament is the Senate which has 11 appointed members, the majority of which are appointed by the Prime Minister. Administrative divisions Saint Lucia is made up of 10 districts. The districts were created and named by French colonials, and the British chose to keep the names in an anglicised form.
