Johnson's visit to Scotland yesterday didn't go so well

and correctly said that the Johnson policy of pushing for a no deal Brexit will hasten the breakup of the UK, not least in NI. The DUP are getting it in the neck from the big Unionist farmers and businesspeople, and I expect the pressure to ramp up as a no deal Brexit approaches. We'll all suffer on the island of Ireland, but the North will be hit far harder. For example, a lot of NI trucks get on the M1 motorway down to Dublin Port or Rosslare, but they'll be stopped for hours with a new hard border put in place and all the added paperwork.

The irony is that the backstop would be less of an issue if there was a joint customs on the island of Ireland, but the DUP blocked it.
