Because they voted in parlaiment to trigger article 50 and stated in their manifesto they would respect the result ?
So if they were such hardened remainers they should never have voted to trigger article 50 in which it gave the possibility of leaving with no deal
Who had it in their manifesto?
Do you mean Corbyn’s Labour, Corbyn who’s a leave supporter?
The fact of the matter is, people have decided what type of Brexit they want the wrong side of the referendum. Which means the rhetoric about free trade and a Norway style deal, the likes of Farage said, convinced many people that it was a good idea and now some people are choosing to decide they want a No Deal.
It’s not the majority that want No Deal though which is going to cause the issue.
Nothing now will be Brexit enough for some and you should have quit whilst you were ahead and they should have either taken the WA or Common Market 2.0.
