Amalgamations -- Amalgamations carried out
The amalgamations carried out under the Act differed slightly from the original scheme announced in 1966 . In Yorkshire , The North and East Riding constabularies were combined with York City Police , while the borough forces of Hull and Teesside were allowed to continue unmerged . Stockport Borough Police were amalgamated with the Cheshire Constabulary instead of with Manchester and Salford , and the scheme for a Tyneside force was dropped when the Local Government Commission 's recommendations were not carried out . Instead Northumberland Constabulary was merged with the two county boroughs north of the Tyne , and Durham Constabulary absorbed those on south Tyneside .
The Police Act 1964 (1964 c.48) was an Act of the Parliament of the United Kingdom that updated the legislation governing police forces in England and Wales, constituted new police authorities, gave the Home Secretary new powers to supervise local constabularies, and allowed for the amalgamation of existing forces into more efficient units.
