Doom merchants, the lot of you. Give Northern Ireland to the Republic, where is belongs, and send all the bloody decenters back to Scotland where they come from.
Hard not to be a doom merchant given the utter fuck-up that is Brexit. I'm fairly sure too that there are dissenters outwith Scotland, and hope that enough of them will be MPs who act to prevent 'no deal' recognising that the current government can't be trusted since their incompetence is now impossible to ignore or forgive.
If 'no deal' is prevented by legislation and the current 'deal' founders in Westminster then the impasse might well need a 2nd referendum to resolve it. That would, for me, be preferable to a GE since the result of that might not be a resolution to the Brexit stalemate unless the Tories get a working majority (and hopefully not): if not, it seems impossible to forecast a future GE should Brexit being binned in the interim, since who knows what the fall-out might be on both the Tories and Labour parties prior to the next GE. If a 2nd referendum did return a Brexit outcome then it would obviously happen, be it 'deal' or 'no deal', and I think the break-up of the UK would follow (every cloud etc).
I hope, like Jeremy, that Article 50 will eventually be rescinded - and if so we have the Scottish courts to thank for that option being available to us, since the Tory government tried and failed to stop the case proceeding.
