Just to shine light on the pretense that their agenda is anything other than to remain in the EU, and that they are only pretending their position is to avoid a No Deal Brexit - they had the opportunity to vote for Mrs May's deal, which was Remain in all but name, and they voted against. They were greedy to have it all. Now they are worried they will end up with nothing.
And so they dress themselves in constitutional robes, when it is really all about their own desire to disregard the will of the people. And they find themselves suddenly with less room to manoeuvre.
These are Remainers pretending to represent the middle ground. They don't. They want to stay in the EU regardless of the referendum. They disregard all of those who want to leave.
