THIS is my first column in a while and since I last wrote about Brexit, things have become clearer.

Specifically, Theresa May has managed to do something few imagined - uniting many Remainers and Brexiters against a Brexit deal that has taken years to negotiate.

I wrote earlier this year we appeared to be heading for a constitutional crisis, and now here we are on the verge of it.

What was the PM thinking? Did she seriously think her deal was ever going to get the support of Parliament?

City MP Robin Walker seems to think so telling the Worcester News recently: "By the time it goes before Parliament next month it will have the support of the government and the EU.”

That has proved true with events in Brussels over the weekend, but on the Parliament vote he added: "It was going to be tough - I do think it will get through."

Right now, that is well wide of the mark. The numbers simply are not there if, as it currently looks like, DUP MPs, ERG group MPs, and the opposition parties don't vote for it. At that point we would be in that unchartered territory of a constitutional crisis. In effect the will of the people has not been carried out, because Parliament hasn't delivered on the referendum result.

So what could happen? In a time when political predictions are impossible to make here's my attempt.

Firstly, there is a second vote in Parliament, with even more pressure put on MPs with talk of the "national interest". Would some MPs crumble at that point? Maybe, but unlikely.

Secondly Theresa May, who has staked her premiership on getting a deal, surely comes under pressure to resign. If we have a leadership contest, after the 48 letters finally emerge, that likely happens in January.

At that point whoever is the PM is faced with political deadlock in the Commons and as far as I can see only two solutions to solve it.

The first is to call a general election, with the aim it gives a majority able to deliver a Brexit deal. But would a PM call one if they are behind in the polls?

The second is the People's Vote second referendum, something that has been constantly ruled out.

As it stands, I see only one way this ends. Time runs out and Britain leaves next March with no deal.
