Bristol City Council is a unitary authority and ceremonial county in England.
Originally formed on 1 April 1974 as a non-metropolitan district as a result of the Local Government Act 1972 (with initial elections taking place in 1973).
It was envisaged that Bristol would share power with Avon County Council, an arrangement that lasted until 1996 when it was made into a unitary authority by the Local Government Commission for England, which abolished the county of Avon and gave Bristol City Council control of Avon Council's responsibilities.
[1][2] A single party must occupy more than half of the councillor seats to have control.
It is possible for a party to control the council without a majority, such as when Labour councillors dissolved their coalition with the Liberal Democrats in February 2009, leaving the Liberal Democrats to form a minority leadership.
