The DUP have an ambivalent stance on a border with the Republic. They don't want a hard border, but are OK with a soft technological border, but not any sort of customs union. I don't know if this kind of soft border can work as it doesn't exist anywhere else. The DUP won't entertain any “regulatory alignment” that ties them to the Republic differently than the rest of the UK. Can self interest overcome their historical intransigence? Would they precipitate a GE that could see them lose their influence and £1b? Yes I think they would do that. The only hope, it seems to me, is that May can cobble together some sort of kind of soft border that is not seen as a customs union for the whole of the UK and the EU.Because they’d have to have a border with Ireland. If we crash out that’s the inevitable consequence.
