Cities of London and Westminster (also known as City of London and Westminster South from 1974 to 1997) is a constituency returning a single Member of Parliament (MP) to the House of Commons in the United Kingdom Parliament. It is a borough constituency for the purposes of election expenses and type of returning officer. As with all constituencies, the election is decided using the first past the post system of election. Since its creation at the 1950 general election, the constituency has 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. These changes came into force from the 1950 election. Boundary changes No alteration was made by the First Periodical Report on constituency boundaries in 1954. In the Second Periodical Report in 1969, the Boundary Commission wrote that their initial feelings were that "except for a minor alteration to follow a new ward boundary" they felt that there was "no reason to disturb" the constituency, and they received no objections to this proposal. Westminster City Council later suggested that the constituency could be more accurately named as 'The City of London and Westminster South'; the Boundary Commission found opinion divided and left the name
