...this is all about the backstop. The backstop is why we haven't got a Withdrawal Agreement through Parliament. Yet.
In my view, if we have to Leave, NI should be a special economic area with a "border in the sea", that is any customs checks happening before/at arrival on mainland Britain from NI. DUP hates this. I think it's an opportunity for them to define NI as separate to Ireland before the inevitable demographic change makes unification the likely course.
What's your idea?
