The Royal Commission on Local Government in Greater London was established in 1957 and the report was published on 19 October 1960. It proposed 52 "Greater London Boroughs" with a population range of 100,000 to 250,000. This was made up of a mixture of whole existing units, mergers of two or three areas, and two boroughs formed as the result of a split. In December 1961 the government proposed that there would be 34 boroughs rather than 52, and detailed their boundaries. The proposed number was further reduced to 32 in 1962.
