How do Welsh Westminster polls differ from Senedd polls?

Welsh Westminster polls measure voting intention for UK Parliament elections using first-past-the-post. Senedd polls measure voting intention for the Welsh Parliament, which from 2026 uses a closed-list proportional representation system with 16 constituencies electing 6 members each. Voters often support different parties at each level.

When is the next Welsh election?

The next Senedd (Welsh Parliament) election is scheduled for 2026. It will be the first election under the new electoral system with 96 members elected by proportional representation across 16 constituencies. For Westminster, Wales elects 32 MPs at the next UK general election.
