You'd rather it failed ?
I can predict that the Labour Party will oppose it. Why ? Because Labour are busily proceeding with their wrecking spree.
Labour threw out Mrs May's deal no less than THREE times. The reason ? The backstop clause.
Boris has carved that clause up, removed it from contention. Parliament SHOULD have altogether more reason to ratify this latest version of a deal than they had the last one.
The truth, though, is that although the Labour opposition insist we should only leave the EU with a deal .. Labour will happily oppose any that surfaces. Watch them oppose this one.
I daresay that the EU will do likewise. They wanted the backstop, because its inclusion worked for them. Its absence will not please them.
