But almost certainly at the next GE more people in Scotland will vote for parties opposed to independence than for it.
I'm not sure even the SNP really wants a referendum on independence that gives only a 52% vote in favour, and it wouldn't get Scotland back into the EU. But that's the problem - Starmer's approach of realism (Brexit has done for us but we don't need to disengage from EU laws) versus what may be a fantasy of rejoining (Spanish or other veto, is there a lot of sympathy for Scotland, if they let Scotland rejoin that would make it harder to get whole UK support to rejoin - if they ever want us back).
Realpolitik time.
