Metropolitan area and County of London (1832–1965)

The Reform Act 1832 gave representation to the London metropolitan area from eight parliamentary boroughs, known as the metropolitan boroughs. This was expanded to ten boroughs in 1868. The Redistribution of Seats Act 1885 extended the area of parliamentary boroughs to the Metropolitan Board of Works area.

Greater London (1965 to current)

1965 to 1974

Despite Greater London being created in 1965 the old constituency boundaries remained in place until 1974.

1974 to 1983

When Greater London was created in 1965 the existing constituencies crossed county boundaries. The constituency review reported in 1969, and was implemented for the February 1974 election. All 92 constituencies were contained within Greater London and each were within a single London borough, with the exception of the City of London and Westminster South. They were all borough constituencies. The constituencies were also used as electoral divisions for the Greater London Council from 1973 to 1986.
The constituencies were redrawn for the 1983 election. All 84 constituencies were contained within Greater London and each were within a single London borough, with the exception of the City of London and Westminster South. They were all borough constituencies.
The constituencies were redrawn for the 1997 election. All 74 constituencies were contained within Greater London. Constituencies crossed borough boundaries between Bexley and Greenwich; Ealing, and Hammersmith and Fulham; Kensington and Chelsea, Westminster and the City of London; Kingston upon Thames and Richmond upon Thames; Lambeth and Southwark; Newham and Tower Hamlets; and Redbridge and Waltham Forest. They were all borough constituencies.
The constituencies were redrawn for the 2010 election. All 73 constituencies are contained within Greater London. Constituencies cross borough boundaries between Barking and Dagenham, and Havering; Brent and Camden; Harrow and Hillingdon; Kensington and Chelsea, and Hammersmith and Fulham; Redbridge and Waltham Forest; Bexley and Greenwich; Bromley and Lewisham; Kingston upon Thames and Richmond upon Thames; Lambeth and Southwark; and Westminster and the City of London. They are all borough constituencies.
The Boundary Commission for England submitted their final proposals in respect of the Sixth Periodic Review of Westminster Constituencies in September 2018. Although the proposals were immediately laid before Parliament they were not brought forward by the Government for approval. Accordingly, they did not come into effect for the 2019 election which took place on 12 December 2019, and which was contested using the constituency boundaries in place since 2010.
Under the terms of the Parliamentary Voting System and Constituencies Act 2011, the Sixth Review was based on reducing the total number of MPs from 650 to 600 and a strict electoral parity requirement that the electorate of all constituencies should be within a range of 5% either side of the electoral quota.
On 24 March 2020, the Minister of State for the Cabinet Office, Chloe Smith, issued a written statement to Parliament setting out the Government's thinking with regard to parliamentary boundaries. They propose to bring forward primary legislation to remove the statutory obligation to implement the 2018 Boundary Review recommendations, as well as set the framework for future boundary reviews in time for the next review which is due to begin in early 2021 and report no later than October 2023. It is proposed that the number of constituencies now remains at the current level of 650, rather than being reduced to 600, while retaining the requirement that the electorate should be no more than +/- 5% from the electoral quota.
