The Metropolitan Police District (MPD) is the police area which is policed by the Metropolitan Police Service in London. It currently consists of the Greater London region, excluding the City of London. The Metropolitan Police District was created by the Metropolitan Police Act 1829 as an ad hoc area of administration because the built-up area of London spread at the time into many parishes and counties without an established boundary. The district expanded as the built up area grew and stretched some distance into rural land. When county police forces were set up in England, those of Essex, Hertfordshire, Kent and Surrey did not cover the parts of the counties within the MPD, while Middlesex did not have a county force. Similarly, boroughs in the MPD that elsewhere would have been entitled to their own police force did not have them. The MPD was originally defined in reference to civil parishes and in 1946 was altered to correspond to local government districts. The MPD has been used for other purposes during its existence, such as the boundary for coal tax and as a 'Greater London' statistical unit. When the Greater London Council was established in 1965, the MPD was expanded to include all of its territory, though some areas that did not become part of Greater London continued to be within it. In 2000, when the Greater London Authority was formed, the outer boundary of the MPD was retracted to coincide with Greater London and the neighbouring county forces then became responsible for those areas outside Greater London. The MPD now consists of the 32 boroughs of Greater London (including the City of Westminster), while the City of London is served by the City of London Police. History Creation The Metropolitan Police District was defined in the schedule of the Metropolitan Police Act 1829 as an approximately circular area within a seven-mile (11-kilometre) radius of Charing Cross, which was divided into four districts and 17 police divisions. It consisted of parts of: 1840 revision There have been numerous changes to the boundaries of the MPD, and of the divisions therein. The Metropolitan Police Act 1839 recognised that the "boundary is... very irregular" and made it lawful to add any place in the Central Criminal Court District and also "any part of any parish, township, precinct or place" not more than 15 miles (24 km) from Charing Cross.
