Politics of the Pitcairn Islands takes place in a framework of a parliamentary representative democratic dependency, whereby the Mayor is the head of government. The territory's constitution is the Local Government Ordinance of 1964. In terms of population, the Pitcairn Islands is the smallest democracy in the world.
The government's administrative offices are in Auckland, New Zealand.
The Queen is represented by the Governor of the Pitcairn Islands, who is the British High Commissioner to New Zealand, currently Jonathan Sinclair. A non-resident Commissioner, appointed by the Governor, serves as the Governor's Representative to the territory. The Commissioner is responsible for the day-to-day administration of the island as well as for its economic regeneration, and also serves as the liaison between the Governor and the Island Council. As both the Governor and the Commissioner do not live on the island, its daily affairs have since 1999 been taken care of by the mayor of Pitcairn. The Island Magistrate is appointed by the Governor. The Chairman of the Internal Committee is an elected official. Until 30 October 2004, the mayor was Steve Christian; after his rape conviction on October 24, 2004, Christian was dismissed (after refusing to resign). His sister Brenda Christian was selected by the Island Council to be mayor for November and December 2004, until an election was held. Jay Warren was elected on 15 December 2004. The island Mayor is elected by popular vote for a three-year term. The current mayor is convicted child rapist Shawn Christian.
