First Minister cancels Independance speech as rumours grow he is about to resign.
Pretty clear his days are numbered and he either goes now or they vote no confidence in him.
He's fucked either way. Resigning is his best bet. It is either a long drawn out death by a 1000 cuts, death by 65+ cuts, or jump.
If it goes to no confidence he's toast.
The greens have nothing to lose, and nothing to gain, they'll take a new election. As would Labour, who will think they can gain big. The tories should be shittong themselves, but, they'll care more about fucking over the snp than their own positions.
If it doesn't, he's on borrowed time and will still face a no confidence vote first contentious issue available.
