What arrangements? Nobody knows. Theresa May is going to Northern Ireland, and then a meeting with Juncker on Thursday.
Europe and Ireland won't let go the backstop, and parliament won't accept it.
If she's got nothing new, and she's failed the mandate she instructed parliament to give her, she will have to resign.
All she's done is waste two years and about 2 billion quid.
That's what happens when you elevate ignorance and bloody-mindedness to a virtue.
