The city is run by a municipal corporation, the Brihanmumbai Municipal Corporation (BMC) which takes care of the civic duties. The head of the corporation is the Mayor. Although he is voted to power, his role is largely ceremonial. The person with the actual executive powers is the Municipal Commissioner, an IAS officer.
The city has its own police department, the Mumbai Police. The Police Commissioner heads the police force, and is appointed by the state government. Since the city is also composed of two districts, two District Collectors are also appointed. Their role is largely curtailed as compared to their rural counterparts. Their job is to approve new construction and oversee national elections.
