I'm sure they'll style it a social democrat, but almost certainly yes. May well be Swinney as caretaker until contest is done even. I wouldn't be surprised to see Kate Forbes take over, then ask Holyrood for an early election to see if she get a mandate. We just had a Muslim, so I can't see her Christianity interfering - and she's likely to lead a minority government anyway
Humza was very explicit in wanting to continue with the progressive slanted agenda. Forbes can't even commit to sounding like a centrist. She absolutely will lead with her right wing interpretation of Christianity.
