What would be the point of a people's vote if the EU treats the result with the same contempt as they treated the last one.I cant see any possibility of a no deal -if time runs out then article 50 could be revoked.
Even if time runs out, the EU have been know to 'stop the clock' -when it suits them.
I guess there will be either a deal worse than we currently have or a peoples vote.
So the payment whether due or not in event of a no-deal is academic.
