I don’t think that Wales would vote for independence because there’s not the stomach for it. Yet. I think if Scotland go for it and seem to be making a success of it then that would alter significantly. I don’t think that the size of the country matters as there are are many example of countries with populations as small or smaller than Wales who are surviving just fine. Take the Baltic states for example, and look who they’ve got for a next door neighbour!If Nicola does well at the coming elections she will force a referendum. Boris will try to win support with promises of billions but why should the Scots believe him.
Wales will not vote for independence as they are too small a state.
NI is a problem that no one wants, the Republic don't want a United Ireland and a referendum would reject it too.
