"They could pick up seats in Scotland if the SNP continue to implode."
I think that's a given. The SNP is a charisma and brains vacuum these days. They will probably suppress the turnout here to even lower levels than Starmers does down south which will benefit all the other parties. It's some achievement: they had everything going for them and yet managed to throw it all away to such an extent that any self-respecting Nationalist would rather not vote than vote for them.
