Stephen Farry of Alliance has been discussing this on Twitter today (@ StephenFarryMLA). Some quotes:
Interesting+ encouraging. Enhanced devolution, NOT change in NI constitutional position. Must be full Single Market, compliance with EU law needs to be guaranteed + something needs sorted on Customs Union. See Alliance proposals.
Theoretically, this could be done directly by Westminster in relation to the devolved space. If done through any functioning Assembly, then could be legal requirement to comply with EU law. In any event, ensuring full compliance is overwhelmingly in NI economic interest.
Re today’s speculation re NI in Brexit talks, lots of people are expressing scepticism over how it can work with a dysfunctionalAssembly. But for anyone who supports a special anything, it will in practice involve more devolved powers. So sorting Brexit & Stormont go hand in hand
Obviously, he's much better infomed than any of us, but I can't say I share his optimism.
