What about this scenario...
UK including NI stay in the Customs Union for a transition period after Brexit date. NI stays in indefinitely.
That would give UK time to sort out their trade deals with other countries including EU. Who knows what will happen in the transition period, an election, DUP outside the tent, whatever.
It is all happening far too fast I think. Time to give space and draw a breath.
The DUP will have the support of a few mavericks on their stance today, they certainly will not have brought the North Antrim farming community (who support them, or did) with them today and many others too.
I am very disappointed that the DUP without any mandate has scuppered this. But I am sure they are delighted with themselves. Fair enough it was within their gift to do this, not democratically I don't think, but strategically.
They should bring in abortion and gay marriage forthwith if they want everything aligned with the UK shouldn't they.
I wish someone with cojones would put that to them. But I suppose they will respond that their stance is purely on a Brexit trade and political basis. Sigh.
