Editing Middlesex (section)

===Creation of Greater London===
The population of inner London (then the [[County of London]]) declined after its creation in 1889 as more residents moved into the outer suburbs. In the [[Interwar Britain|interwar years]], suburban London expanded further, with improvement and expansion of public transport,<ref name="wolmar"/> and the setting up of [[Second Industrial Revolution|new industries]].

After the [[Second World War]], from 1951 to 1961, the populations of the administrative county of London<ref name=lcc_pop>{{cite vob |population=http://www.visionofbritain.org.uk/data_cube_table_page.jsp?data_theme=T_POP&data_cube=N_TPop&u_id=10041790&c_id=10001043&add=N |name=County of London |accessdate=20 February 2008 }}</ref> and of inner Middlesex were in steady decline, with population growth continuing in the outer parts of Middlesex.<ref name=census_1961/><ref name=mdx_pop>{{cite vob |population=http://www.visionofbritain.org.uk/data_cube_table_page.jsp?data_theme=T_POP&data_cube=N_TPop&u_id=10061441&c_id=10001043&add=N |name=Middlesex |accessdate=20 February 2008 }}</ref> According to the 1961 census, Ealing, Enfield, Harrow, Hendon, Heston & Isleworth, Tottenham, Wembley, Willesden and Twickenham had each reached a population greater than 100,000, which would normally have entitled each of them to seek [[county borough]] status. If this status were to be granted to all those boroughs, it would mean that the population of the administrative county of Middlesex would be reduced by over half, to just under one million.

Evidence submitted to the [[Royal Commission on Local Government in Greater London]] included a recommendation to divide Middlesex into two administrative counties of North Middlesex and West Middlesex.<ref name="LSE London"/> However, the commission instead proposed abolition of the county and merging of the boroughs and districts. This was enacted by Parliament as the [[London Government Act 1963]], which came into force on 1 April 1965.

The Act abolished the administrative counties of Middlesex and London.<ref>[[London Government Act 1963]], '''Section 3:''' ''(1) As from 1 April 1965—''<br />
''(a) no part of Greater London shall form part of any administrative county, county district or parish;''<br />
''(b) the following administrative areas and their councils (and, in the case of a borough, the municipal corporation thereof) shall cease to exist, that is to say, the counties of London and Middlesex, the metropolitan boroughs, and any existing county borough, county district or parish the area of which falls wholly within Greater London;''<br /> The new enlarged administration became known as the [[Greater London Council]] or its acronym, the GLC.

The former separate (joint) fire and ambulance service of Middlesex, the second largest in Britain after London was largely absorbed into enlarged London organisations under the newly formed GLC, the exception being those areas moving into Surrey and Hertfordshire.
''(c) the urban district of Potters Bar shall become part of the county of Hertfordshire;''<br />
''(d) the urban districts of Staines and Sunbury-on-Thames shall become part of the county of Surrey.''<br />
'''Section 89:''' ''(1) In this Act, except where the context otherwise requires, the following expressions have the following meanings respectively, that is to say—''
<br />
'' 'county' means an administrative county;''</ref> The [[Administration of Justice Act 1964]] abolished the Middlesex magistracy and [[Lord-lieutenant|lieutenancy]], and altered the jurisdiction of the Central Criminal Court.
