Cities of London and Westminster (known asCity of London and Westminster South from 1974 to 1997) is aconstituency^{[note 1]} returning a singleMember of Parliament (MP) to theHouse of Commons in theUnited Kingdom Parliament. As with all constituencies, the election is decided using thefirst-past-the-post system of election. Until the2024 general election, when the constituency electedRachel Blake, aLabour Co-op MP, the constituency had always elected the candidate nominated by theConservative Party.^[3]

Before 1950 theCity of London formed a two-member constituency on its own. TheBoundary 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;^[4][5] the Commission recommended that the borough ofChelsea and theCity of Westminster form a single Parliamentary Borough of Chelsea and Westminster with two divisions.^[6]

In February 1948 the Government brought forward a newRepresentation 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 ofFinsbury andShoreditch.^[7] During debates on the Bill, the Government amended it to substitute a link between the City of London and the City of Westminster.^[8] In introducing the amendment the Home SecretaryJames 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.^[9]

These changes came into force from the1950 election.

No alteration was made by the First Periodical Report on constituency boundaries in 1954.^[10] 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 unchanged when it published revised proposals for two other constituencies within the city. Subsequent representations on the name were received and the Commission decided that, although justified on historical grounds, the name was "not now entirely accurate" and so proposed the renaming as suggested by the City Council.^[11]

In initial proposals during the Third Periodical Review (1983), the Boundary Commission proposed to abolish theSt Marylebone constituency and add four wards from it (Cavendish, Baker Street, Bryanston and Regents Park) to the previous City of London and Westminster South constituency; they provisionally named the result 'The City of London and Westminster'. After a local inquiry, the Regents Park ward was removed, and Hyde Park ward (from thePaddington constituency) was added; unanimous opinion at the inquiry favoured naming the result 'The City of London and Westminster South'.^[12]

For the Fourth Periodical Review (1995), the Boundary Commission paired the City of Westminster with theRoyal Borough of Kensington and Chelsea for consideration. The commission's initial proposals, to expand the constituency by two wards (Bayswater and Lancaster Gate) formerly inWestminster North and to return to the name 'Cities of London and Westminster', were upheld after a local inquiry, despite multiple counter-proposals.^[13]

At the Fifth Periodical Review (in 2007), the initial proposals of the Boundary Commission paired the City of Westminster with theLondon Borough of Brent although they involved only minor changes to the Cities of London and Westminster constituency to take account of new ward boundaries. Widespread objections ("almost universal hostility") to the pairing led to a local inquiry, which decided that Westminster and the City of London should be reviewed separately and not paired with any other borough. The Commission proposed a new Cities of London and Westminster constituency in which the revised Bayswater and Lancaster Gate wards were removed.^[14]

Early proposals made during the initial stages of the postponedSixth Periodic Review of Westminster constituencies proposed linking the City of London to the southern wards ofIslington in a constituency to be known as "The City of London and Islington South".^[15] Most of the Westminster wards were proposed to form part of a Westminster and Kensington constituency.^[16] This proposal was the first to suggest a split between the two Cities in Parliamentary elections since they were joined and proved unpopular in consultation; the Boundary Commission revised them to return the link between the City of London and the City of Westminster,^[17] although the review was subsequently placed on hiatus.

In 2016, the Boundary Commission produced a second attempt at the Sixth Periodic Review. Its proposed Cities of London and Westminster comprises the City attached to Regent's Park and Abbey Road to the north-west, Knightsbridge/Belgravia to the west, and Holborn/Covent Garden to the north.^[18]

Although united for Parliamentary elections, in the London Assembly, the City of London is covered by theCity and East constituency, and the area in Westminster by theWest Central constituency. The Local Government Commission for England argued that "combining the City of London with areas to its east could assist in focussing regeneration eastwards" and linked it with theLondon Borough of Tower Hamlets, theLondon Borough of Newham, and theLondon Borough of Barking and Dagenham.^[19]

The seat covers the entire City of London and most of the City of Westminster lying South of theMarylebone Road and theWestway. In the latter, more residential, city it coversWestminster,Pimlico,Victoria,Belgravia,Knightsbridge,St. James's,Soho, most ofCovent Garden, alongside parts ofFitzrovia,Marylebone,Edgware Road,Paddington andBayswater.

In 1964, theCity of Westminster was created to replace the old Metropolitan Borough of Westminster, which kept the same wards.

TheCity of London consisted of Aldersgate, Aldgate, Bassishaw, Bassishaw, Billingsgate, Bishopsgate, Bread Street, Bridge Within, Bridge Without, Broad Street, Candlewick, Castle Baynard, Cheap, Coleman Street, Cordwainer, Cornhill, Cripplegate, Dowgate, Farringdon Within, Farringdon Without, Langbourn, Lime Street, Portsoken, Queenhithe, Tower, Vintry and Walbrook.

1974–1997: The City of Westminster wards as above, and the City of London, as above.

New boundaries from 1978 meant the following wards from the City of Westminster were used: Baker Street, Belgrave, Bryanston, Cavendish, Churchill, Hyde Park, Knightsbridge, Millbank, St George's, St James's, Victoria, andWest End.

In the City of London, Bridge Within and Bridge Without were combined in 1978 to create Bridge.

1997–2010: The City of Westminster wards as above, plus, Bayswater and Lancaster Gate, and the City of London.

In 2002, aLocal Government Boundary Commission for England review abolished the Baker Street, Belgrave, Bryanston, Cavendish, Knightsbridge, Millbank, St James's and Victoria wards.^[20]

For the2005 general election, the Westminster electoral wards used in this constituency were Bayswater (part), Bryanston and Dorset Square (part), Churchill, Hyde Park, Knightsbridge and Belgravia, Lancaster Gate, Marylebone High Street, St James's, Tachbrook, Vincent Square, Warwick and West End.^[21]

2010–2024: The City of Westminster wards of Bryanston and Dorset Square, Churchill, Hyde Park, Knightsbridge and Belgravia, Marylebone High Street, St James's, Tachbrook, Vincent Square, Warwick, and West End, and the City of London.

Following the2023 review of Westminster constituencies, which came into effect for the2024 general election, the constituency is composed of the City of London and the following wards of the City of Westminster:

• Abbey Road;Hyde Park;Knightsbridge & Belgravia;Marylebone;Pimlico North;Pimlico South;Regent’s Park;St James’s;Vincent Square;West End.^[22]

The new boundaries reflect the local authority boundary review which came into effect in May 2022. The seat was expanded to bring the electorate within the permitted range by adding the Abbey Road and Regent's Park wards which were previously in the abolished constituency ofWestminster North.
