2023 Periodic Review of Westminster constituencies

The 2023 Periodic Review of Westminster constituencies is the current cycle of the process to redraw the constituency map for the House of Commons. The process for periodic reviews of parliamentary constituencies in the United Kingdom is governed by the Parliamentary Constituencies Act 1986, as amended by the Parliamentary Voting System and Constituencies Act 2011 and subsequently by the Parliamentary Constituencies Act 2020.[1] This review is the successor to the Sixth Periodic Review of Westminster constituencies, which was ultimately abandoned after two successive proposals by the Commissions failed to pass into law.

Under current legislation, the four Boundary Commissions of the United Kingdom are required to report on their next review of the boundaries of parliamentary constituencies before 1 July 2023.[1] In order to meet this deadline, the Commissions began their work on 5 January 2021.
