The Greater Manchester Combined Authority (GMCA) is the combined authority of Greater Manchester, England. It was established on 1 April 2011 and consists of eleven indirectly elected members, each a directly elected councillor from one of the ten metropolitan boroughs that comprise Greater Manchester together with the interim Mayor of Greater Manchester. The authority derives most of its powers from the Local Government Act 2000 and Local Democracy, Economic Development and Construction Act 2009, and replaced a range of single-purpose joint boards and quangos to provide a formal administrative authority for Greater Manchester for the first time since the abolition of the Greater Manchester County Council in 1986.
