European Union (Withdrawal) Bill

The Minister speaks of common approaches across the EU. We have heard today about the possibility of an alignment between the Northern Irish arrangements and those of the Republic and the rest of the EU. How will we retain those common approaches if, for instance, the UK negotiates a new trade deal post-customs union, and we end up with circumstances in which that would, or would not, apply to Northern Ireland? How on earth can the Minister reconcile that with the offer that the Government have been talking about today?
