to begin its review of the parliamentary constituencies in Wales, with the commission required to publish its final recommendations for boundary changes by 1 July 2023. By December 2021, the commission published the responses collected during the consultation period, and then conducted a six-week 'secondary consultation. Unlike the previous periodic review, the total UK constituencies was kept at 650.
When proportionally dividing the total 2021 electoral population of the United Kingdom using a statutory formula between the constituent countries of the UK, it results in England having 543 constituencies, Scotland having 57, Wales having 32 and Northern Ireland with the remaining 18. Each constituency recommended to have no more than 77,062 electors and no less than 69,724.
The figure from Wales is calculated to be 8 seats lower from the total constituencies used for the 2019 UK general election when there were 40 constituencies, the largest decrease of any UK country or region. Wales has one 'protected constituency' not subject to UK electoral quotas,

The decrease in constituencies in Wales has been described by the commission to represent "the most significant change to Wales's constituencies in a century", and the commission has no control over the number of constituencies in Wales. The final proposal published by the commission no longer required parliamentary approval and the recommendations in the final report were implemented automatically, however the second consultation period allowed public hearing about the proposals. The commission stated that it tried wherever possible to use existing local government boundaries, such as those of existing constituencies and principal areas.
Final recommendations

The final recommendations on the new constituencies in Wales were published on 28 June 2023 by the

This followed years of proposals and consultations since 2021, with initial proposals published in 2021
and revised in 2022.

New – Did not exist previously with either the name or boundaries.
Expanded – Keeps name but gains wards.
Redefined – Keeps name but with other altered boundaries.
Revived – Former constituency revived under the same name(s).
