"votes to leave in a referendum" -- what if SNP or other indy parties treat a general or Scottish election as a de facto referendum and win most of the votes?

What happens if there is a Scottish government that claims to be independent but is not recognized by London as such?

@BrunoParga

I guess in that case it depends on how the international community sees it. If the EU, USA and similar treat Scotland as if it is independent then “yes”, otherwise “no”.

Update: I’ve decided that the check for this will be whether or not Scotland has a separate seat to the UK at the UN.

@DaisyWelham the UN's procedures can surprise, and I'm not an expert, but it appears that the UK has a veto on UN membership for new states:
