Birmingham City Council is the local government body responsible for the governance of the City of Birmingham in England, which has been a metropolitan district since 1974. It is the most populated local council area in the United Kingdom (excluding counties) with 101 elected councillors representing over one million people, in 69 wards. The council headquarters are at the Council House in the city centre. The council is responsible for running nearly all local services, with the exception of those run by joint boards. The provision of certain services has in recent years been devolved to several council constituencies, which each have a constituency committee made up of councillors from that district. It is part of the West Midlands Combined Authority.
