Attorney General tries to bridge the gap
Conservative PM and Attorney General Geoffrey Cox spoke to the EU's Barnier to try to get some changes to the agreement in the hopes of getting it through parliament. He raised the idea of an "arbitration panel" that would determine if the two sides were acting in good faith under the backstop. He also proposed a mini-backstop that would limit the mechanism to only cover border infrastructure.
Both were rejected by Barnier.
I think it's pretty clear that the EU is going to let May hang.
