I wonder if Johnson won't sanction it sooner than people think. There'll be Brexit uncertainty for a while so no one in Scotland knows whether they're better off inside the the EU or UK, and whilst he won't want to wear the badge of being the PM who saw the break up of the union, come the next election, will anyone in England give a shit? After all, we'll be thriving from all our new trading relationships that are going to be sorted in the next year and it's 50 less MPs to vote against him.
