Wales was redrawn into sixteen constituencies, each returning six members, expanding the chamber from sixty to ninety-six. Every figure on this page describes a Wales now structured for the first time around this new geography.

The Constitutional Picture
“A national commission, not a referendum.”
First-term position
Plaid Cymru continues to support Welsh independence. The party has stated that an independence referendum is not proposed during a first term. Instead the manifesto commits to a national commission with a defined budget to examine future constitutional options, including further devolution and the foundations for a future white paper on independence.
WalesDecided.co.uk will track the commission's establishment, terms of reference, membership and outputs.
