Its not clear from you response what happened to the postal votes up-north. How were they counted?
How should Labour have voted on the Deal? I’ve read Labour couldn’t vote against the Deal because it would result in No Deal! Except Parliament wouldn’t support No deal! And so this means if the vote against the Deal was won, it would result not in No Deal, but an extension of the transition period, until a Good Deal was obtained, unless the EU refused.
