Police authority  A police authority in the United Kingdom is a public authority that is responsible for overseeing the operations of a police force. The nature and composition of police authorities has varied over time, and there are now just four dedicated "police authorities" in the United Kingdom, although the term can refer to various similar successor bodies. Until 2012/13, individual police authorities were maintained for each of the 43 territorial police forces in England and Wales, and for the 8 territorial police forces in Scotland. Police authorities in England and Wales were abolished in November 2012, and replaced with directly elected police and crime commissioners, and those in Scotland were merged in April 2013 to form the Scottish Police Authority as part of the creation of Police Scotland, the single police force for Scotland. The Police Service of Northern Ireland is overseen by the Northern Ireland Policing Board, and two of the three UK-wide special police forces continue to be overseen by individual police authorities. The oversight of the two police forces serving London continues to be implemented via unique arrangements. The introduction of police forces on a national scale in England and Wales began with the Municipal Corporations Act 1835, which required each borough to establish a "watch committee" and thus appoint constables to "preserve the peace". Before the advent of police authorities, the regulatory bodies for police forces confined to a single borough were these watch committees, whilst those for counties from 1889 had been "standing joint committees" (after 1889 some control passed to the elected county council; the joint committee also had magistrates). The Police Act 1964 introduced major reforms to the organisation and oversight of the police in England and Wales, following the report of the Royal Commission on the Police in 1962. The 1964 act abolished the old watch committee system which had come under severe criticism following several high-profile corruption scandals. The act introduced police areas, which would be administrative counties, county boroughs or "combined police areas", consisting of combinations of counties and county boroughs, served by a single force, overseen by an independent "police authority". The new police authorities would consist of two-thirds elected members of county or borough councils, and one-third magistrates. Under the Local Government Act 1972 the remaining borough police forces were abolished, and police authorities consisted of county councillors and magistrates in a ratio of two to one. The Police and Magistrates' Courts Act 1994 altered the composition of the authorities with independent members being added. Typically, a police authority was made up of seventeen members – nine elected members (who were drawn from the local authority or authorities for the force area, and would be reflective of the political makeup of those authorities).
