As Plaid have only been in power in Wales since May 2026 that’s a tad premature M0nica.
I guess your perspective is quite different when you live in a poor ex mining area, for example, of a country which has historically not done well by an English-centric government to how you feel if you’re living in middle England.
For what it’s worth, Wales would not vote for independence currently, I don’t know about Scotland. What is objected to though is English people saying we are not allowed to vote to determine our own destiny - it’s a b….y cheek in fact.
