Streamlining the cities: Government proposals for reorganising local government in Greater London and the Metropolitan counties was a government white paper issued in 1983, by the Conservative government of Margaret Thatcher which led to the abolition of the Greater London Council (GLC) and the metropolitan county councils (MCCs).
The white paper argued that most local services in Greater London and in the six metropolitan counties, were provided by the London boroughs, and by the Metropolitan district councils.
The white paper concluded therefore, that the latter's existence could be justified, whereas the GLC and the MCCs could not.
The white paper concluded that the GLC and the MCCs should be abolished and replaced by a system of joint boards, to take over some of the county council's functions.
The white paper's proposals were largely implemented in the Local Government Act 1985.
