Key Changes in the 2026 Senedd Election
Date: Thursday, 7 May 2026.
Expansion: The Senedd grows from 60 to 96 members, and Wales is divided into 16 “super constituencies”, each electing six Members.
Here is a quick explanation
• You cast one vote only.
• You vote for a party
• Seats are allocated proportionally based on the share of votes in each constituency.
• Anyone aged 16+ and resident in Wales can vote.
This means every vote directly affects how many seats each party wins, shaping who governs Wales.
