The Police Act 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.

Royal commission A Royal Commission on the Police had been appointed in 1960 under the chairmanship of Henry Willink to "review the constitutional position of the police throughout Great Britain".

The appointment of the commission followed two high-profile scandals involving borough police forces. These exposed problems in the relationship between the chief constable and watch committee of each borough, and disputes between central and local government over the control of local forces. In 1958, following a trial into police corruption in Brighton, the presiding judge stated that the judiciary could have no faith in police evidence until the chief constable had been replaced. Brighton Watch Committee complained that they could not properly supervise the force, as they had no access to the annual report of Her Majesty's Inspectorate of Constabulary, which was sent to the Home Secretary. In 1959, the watch committee of Nottingham suspended the city's chief constable, Athelstan Popkess, when he refused to furnish a report on his investigations into alleged corruption of councillors. Details of the investigation were however leaked to the press on the eve of municipal elections. The committee were subsequently forced to reinstate Popkess when the Home Secretary, Rab Butler, threatened to withdraw central government funding.

Among the particular subjects for investigation by the commission were: The constitution and functions of police authorities The accountability of police officers including chief constables The relationship of the police to the public and procedures for dealing with complaints The remuneration of police constablesRoyal Commission on the Police 1960: interim report, BOPCRIS website

The commission published its final report on 31 May 1962. This recommended an urgent review on the number and size of police areas. Among its recommendations were: No single national force was to be formed, but central government should exercise more powers over local forces Retention of small police forces of between 200 and 350 officers "justifiable only by special circumstances such as the distribution of the population and the geography of the area" The optimum size for a police force was more than 500 members, with the police area having a population of at least 250,000 There was "a case" for single police forces for major conurbations A large reduction in the number of forces in Scotland was needed, to between 20 and 33

The commission noted that of 158 police forces in Great Britain, 97 had an establishment of less than 350.

Provisions The act received royal assent on 10 June 1964. Among its provisions were:

England and Wales, outside London, was to consist of "police areas". These were to be administrative counties, county boroughs or "combined police areas", consisting of combinations of counties and county boroughs. The Home Secretary had the power to force compulsory amalgamation schemes from 1 July 1964. New "police authorities" were to be established: these were to be known as watch committees (in boroughs), police committees (in counties – replacing joint standing committees) or combined police authorities. Police authorities were to consist of two-thirds elected members and one-third magistrates. Previously all members of watch committees had been councillors or aldermen, while county joint standing committees were fifty per cent county councillors and aldermen, fifty per cent magistrates. The police authorities had fewer powers than their predecessors, especially the boroughs, with the Home Secretary taking on more supervision than before. The authority were required to maintain an efficient police force, but had no operational role. Chief constables were given the power to appoint, direct and control special constables. The chief constable could appoint police cadets with the permission of the authority. The chief constable was required to make an annual report to the police authority. A police authority could also request other reports on policing in the police area. Police authorities were empowered to choose chief constables, deputy and assistant chief constables from a Home Office shortlist. They could also require the chief constable to retire, subject to the Home Secretary's approval. The Home Secretary could order a complaint against a police force to be investigated by officers of another force.
