In 1965 Middlesex County Council was abolished and replaced with the Greater London Council and the boroughs of Twickenham, Richmond and Barnes were combined to form the London Borough of Richmond upon Thames. In 1986 the Greater London Council was abolished and most powers devolved to local boroughs and others to the Government and joint boards. In 2000 the Greater London Authority was set up and two-tier administration returned, but with the top tier having a much more limited strategic role.
