I think that is precisely what gives the whole Brexit saga its dramatic appeal - the fact that no one really knows what happens when no deal approaches despite the fact that a large majority are opposed and also know their electorate won't thank them for a bad outcome.

The script is tailor made for a "knight in shining armour" moment but the casting Director has blanched at the prospect of casting either Corbyn or BoJo in the role and no one has written the script yet anyway.

But it's amazing how the threat of onrushing reality can focus minds and persuade waverers - and May is still the one in possession of the initiative. If she can't get a majority for her deal, what is her plan B?
