Welcome to this bonus episode of Calling Peston as we dissect and debate the result of the Labour leadership contest.

Jeremy Corbyn's reign is over. The Labour Party has a new leader, Sakea Stama. He won the contest with ease, winning 56.2% of the vote in round one,

defeating his rivals Rebecca Long Bailey and Lisa Nandi.

What does that mean for the future of the party? What does that mean for the future of the Conservative Party?

Is Labour on the way back, or has Keir Stama got too steep a hill to climb?

I'm Daniel Hewitt. With me to discuss that and more is our political reporter Sheehab Khan.

Hello, Sheehab.

Hiya. And as ever, our political editor, Robert Peston joins us. Good afternoon, Robert.

Hiya. Robert, let's start with you, shall we? Look, no big surprises here. A big mandate for

Keir-Stama. A new dawn for Labour. What kind of Labour party do you think he will need?

Before we get on to that, I think it is quite important just to mark the significance to this.

I mean, I did say, actually, you know, long before the contest even started that I thought Starma would win,

but back then, it looked as though the left would still do pretty well. It did look as though

their candidate, Rebecca Long Bailey, would give Kirstama a run for his money. And in the end,

he didn't. I mean, he won 56% of the votes

in the first round. That's an absolutely clear mandate. It's quite close actually to what Jeremy

Corbyn got back in 2015. He got 59% of first round votes.

But once you've got 56% of something like, I mean, something like 500,000 people cast their ballots.

I mean, that is in terms of British, you know, modern British party elections.

I mean, that's, you know, actually, I think in the history, history actually of British politics, because in the past, of course, leaders weren't chosen on a sort of one

person, one vote basis. I mean, that is, you know, he has the biggest popular mandate for

any party leader, you know, in modern times.
