Cities of London and Westminster (UK Parliament constituency)
Parliamentary constituency in the United Kingdom, 1950 onwards
Cities of London and Westminster (known as City of London and Westminster South from 1974 to 1997) is a constituency in Greater London returning a single Member of Parliament (MP) to the House of Commons of the UK Parliament. It was established in 1950 in central London. As with all constituencies, the election is decided using the first-past-the-post system of election. Until the 2024 general election, when the constituency elected Rachel Blake, a Labour Co-op MP, the constituency had always elected the candidate nominated by the Conservative Party.
History
Before 1950 the City of London formed a two-member constituency on its own. The Boundary Commission for England began reviewing constituencies in January 1946 using rules defined under the Representation of the People Act 1944, which excluded the City of London from the redistribution procedure; the Commission recommended that the borough of Chelsea and the City of Westminster form a single Parliamentary Borough of Chelsea and Westminster with two divisions.
In February 1948 the Government brought forward a new Representation of the People Bill which removed the right of owners of business premises to a second vote; this would have had the effect of reducing the electorate of the City of London from 12,500 to 4,600. The Bill proposed also to end the City of London as a separate constituency and to merge it with the adjacent boroughs of Finsbury and Shoreditch. During debates on the Bill, the Government amended it to substitute a link between the City of London and the City of Westminster. In introducing the amendment the Home Secretary James Chuter Ede noted that the alterations to the constituencies in Westminster, Chelsea and Kensington had been agreed unanimously at a conference between the Members of Parliament and representatives of the boroughs affected.
