The U.K. has a constitutional monarchy, with the monarch ruling as head of state in 15 other countries, including Canada and Australia. Some degree of autonomy exists within the U.K. countries. In 1999, the National Assembly for Wales, the Scottish Parliament and the Northern Ireland Assembly were established to oversee each country's laws and legislature.
