As usual, we need the advice of our assistant political register, Norman Smith at Westminster to understand what this means, Norman explain this vexed full extension to us.

But what it means, first off is that Boris Johnson's do or die pledged to leave by October.

The 31st is no more.

It is dead.

It is over.

It is finished.

It is not going toe happen.

That is off the table.

So that is the first domestic political consequence off the you decision.

And what they've done is agreed to the extension, which Mr Johnson set out in that letter, which he said was from Parliament but which he was forced and obliged to write as prime minister, seeking a delay to Brexit until January, the 31st.

Now, the you have incorporated into that what's called a flex tension.

In other words, different break points when the you could leave on November, the 31st December, the 31st or January 31st.

If we get a deal ahead of them to be honest, I think there was always a calculation that that would be allowed anyway without the you formally setting out those bench park moments.

But it does now mean that too many no deal would have been taken off the table at least until January.

The 31st which will increase the arguments in the Commons that with no deal parked at least until January, the 31st parliament now has to make a decision on election.

And that is what Boris Johnson will be trying to argue today and over the immediate days ahead as he tries to secure this general election ahead of Christmas.

And as he tries obviously to to control the narrative is coming back to the first point you have made.

I mean, he did say was going to do or die in a ditch.

And there were all these dire warnings from from the Hard Brexiteers about what awful chaos would ensue if we didn't get out of the E view by the 31st of October and so on.

I mean, how are they all going to kind of back out of that?

I suspect what you'll hear from them is what we've already heard, which is Boris Johnson did his best, but was thought ID by Parliament.

The question is, how do voters read that?

Do they think?

Well, this is a man who said he was going to do this and hasn't done it.

In other words, whether he has punished particularly, I suspect by the Brexit party, he will say, Well, if you can't trust Boris Johnson just like Theresa May, who promised will be out on March 31st he promised with the after October the 31st.

I'm just like Theresa May.

He hasn't got his deal and he hasn't got us out.

The other possibility is that voters are more sympathetic towards Boris Johnson because he has, as we know, tried all sorts of mechanisms to force Parliament to make a decision ahead of 31st.

Maybe they take a more charitable view that he's done his best, but it is a risk on the risk of calling a general election if he manages to call one without Brexit being resolved is he is punished for not resolving Brexit.

So in a way, yes, you know it buys more time, but it also creates an element of uncertainty for Boris Johnson because he now campaigns for a general election in the knowledge that he has failed in his signature policy when he stood for the Tory leadership.

Normal, much more from you later for now, thanks so much.
