Wales is subject to the administration of both the UK Government in Westminster and also the National Assembly for Wales in Cardiff.
The UK Government retains responsibility for non-devolved topics, but the National Assembly has powers to make legislation in devolved topics such as health, education, agriculture, local government, environment, and culture.
Wales is subdivided into 22 unitary authorities, which in turn are divided into electoral divisions and communities.
