Review of Senedd constituency boundaries in Wales

The Democracy and Boundary Commission Cymru (‘the Commission’) is responsible for reviewing Senedd constituency boundaries in Wales. This report contains the Commission’s initial proposals for Senedd constituencies in Wales. It is the beginning, not the end, of the Commission’s review process. These are the Commissions initial views. The Commission look forward, during the review process, to hearing from the people of Wales on how these proposals might be amended and revised.

In September 2023, the Welsh Government announced a bill to amend the Senedd constituencies. The Senedd Cymru (Members and Elections) Bill was introduced on 18 September 2023. The bill received royal assent on 24 June 2024. The new legislation will mean that the Commission will have to return 16 Senedd constituencies which are formed by combining 2 contiguous UK parliamentary constituencies. Each constituency will be represented by 6 Members of the Senedd, bringing the total number of members to 96.

The review has to be completed by 1 April 2025, and will use the 32 new UK Parliamentary constituencies in order to create 16 new Senedd constituencies. The Commission’s recommendations will be implemented by the ‘automaticity’ rule. As such, the recommendations will not require Senedd approval. The final decisions must be implemented as set out in the Commission’s final report.
