I think that would be hard to do Drew. I can understand why Scotland wants independence but struggle to see how it would work in you stayed in the EU while England and Wales left. I know it is historic treaty but Scotland signed the Treaty of Union way back when

so they need permission from Westminster to hold another referendum - BJ ain't going to give it because it would break up the UK.

Northern Ireland, however, did not sign such a treaty so I suspect a United Ireland will happen first by means of a border poll, the reunification of Ireland - time will tell. I hope it is a peaceful transition.
