Places of deposit for hard copies of proposals
We deposit a hard copy of our proposals for new constituencies in at least one public place in the relevant proposed constituency. We have published a full listing of places of deposit (Excel document) in the download area at the bottom of this page. Please be aware that some public places have limited opening hours, and additional access restrictions may also be in place locally to protect against the spread of COVID-19. Anyone interested in viewing these hard copies is therefore strongly advised to contact the place of deposit directly (not the BCW) to confirm the particular access arrangements in place for that site.
General Information about the 2023 Review
Following the passing of the Parliamentary Constituencies Act 2020 in December 2020, and the publication of the relevant Parliamentary electorate data in January 2021, we began a new review of all Parliamentary constituencies in England. We refer to this as the ‘2023 Review’, as we are required to report with our final recommendations by 1 July 2023.
Applying the statutory formula to the electorate figures means the total 650 constituencies is distributed during the review to the four parts of the UK as follows:
- England = 543 (includes two ‘protected’ constituencies on the Isle of Wight);
- Scotland = 57 (includes two ‘protected’ constituencies for specified Scottish islands);
- Wales = 32 (includes one ‘protected’ constituency on the Isle of Anglesey); and
- Northern Ireland = 18
Application of the statutory formula results in a decrease of 8 Parliamentary Constituencies across Wales.
Application of further statutory rules to the published electorate also means that all recommended constituencies must have no less than 69,724 Parliamentary electors and no more than 77,062 (except those ‘protected’ constituencies mentioned above). By law, these electorate figures relate to the electorates as they were on 2 March 2020.
What Happens Now?
On 8 September 2021 we published our initial proposals for how the 32 constituencies for Wales could be drawn up within the legal parameters mentioned above. This commences a statutory consultation period of eight weeks (closing 3 November 2021), when anyone can give us their views on those proposals. We will be particularly interested to hear from people about the extent to which the proposals reflect the local ties in the area, and if people disagree with our proposals, how they think they should be amended.
There are two further rounds of public consultation.
