About the review
The 2023 Review of Parliamentary constituencies was formally launched in January 2021. Due to population changes since the last review, the number of electors in some constituencies is much higher than in others. The Boundary Commission for England (BCE) is required by legislation to ensure that the number of electors in each constituency is more equal; in doing so, the number of constituencies in England will increase from 533 to 543. To implement these requirements, there will be wide scale change to the majority of constituencies.
The BCE will make its final recommendations to Parliament by 1 July 2023. The Government must turn the recommendations of the BCE (and those of the equivalent Commissions for the other three parts of the UK) into an ‘Order in Council’ that implements the recommendations. The constituencies set out in the Order will then be implemented for the next General Election after the date on which the legislation is approved.
The BCE published the initial proposals which was the first time people get a look at what the map of constituencies might look like. This was published on 8 June 2021 and launched an initial eight week consultation, ending on 2 August 2021.
