Cities of London and Westminster (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. 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.
