European Union (Withdrawal Arrangements) Bill

Brexit was a national vote, decided for better or for worse on a national basis. The people of London did not vote for Brexit, but no one is saying they should now be ruled by laws from Brussels. The People of Northern Ireland by a small majority did not vote for Brexit, but Members are saying that we should be ruled by laws from Brussels. That does not stack up. I am simply calling in aid what the Belfast agreement says: the Belfast agreement says key decisions are cross-community. Is anyone denying this is a key decision? If so, why is it not a cross-community vote?
