Your Senedd is Changing
In May 2026, the way you'll vote for Members of the Senedd is changing.
Everyone will get one vote on the 7th May 2026. The new closed list proportional representation system means that you'll be voting for the party.
The seats a party wins is based on the percentage of the vote the party gets. Each constituency will elect 6 Members of the Senedd.
Your new Cardiff constituency has been made by pairing Cardiff West and Cardiff South and Penarth into the new Caerdydd Penarth constituency.
For more information, you can visit the Senedd website Senedd Election and Member Changes
