One of the biggest tests for Labour is next year is in London, says Ian McNichol with reference to the mayoral election. He says Sadiq Khan - who was yesterday chosen as Labour's candidate to fight the election - would be a "fantastic mayor", and applause greets the Tooting MP as he takes to the stage to deliver a short speech.

A huge, and lasting, round of applause and cheers for Harriet Harman, the acting interim Labour - seated in the crowd. Ian McNichol pays tribute to her "tireless" work in pursuit of Labour's values. "Harriet we all owe you a huge debt of gratitude," he tells her. More applause. Mr McNichol also praises her role in boosting female representation in the party.

The challenge for Labour is how to turn the "enthusiasm" the campaign has generated into practical campaigning for Labour, says Ian McNichol as he appeals to those who have taken part not to leave their involvement at just a click of a button and a £3 payment.

Ahead of an election result where most expect him to come out on top, Jeremy Corbyn has been setting out the style of leadership that he wants to adopt. 

He has said, external: "Fundamentally many people are turned off by a political process when the major parties are not saying anything different enough about how we run the economy, and totally turned off by a style of politics which seems to rely on the levels of clubhouse theatrical abuse that you can throw across at each other in parliament and across the airwaves."

But some of you might be getting a slight touch of deja vu. Cast your minds back to December 2005. In his acceptance speech to be Tory leader, David Cameron said:

"And we need to change, and we will change, the way we behave. I'm fed up with the Punch and Judy politics of Westminster, the name calling, backbiting, point scoring, finger pointing."

Iain McNichol says it has been a "free and fair" election, and those who have "cynically tried to subvert our democracy" have been weeded out.

Ian McNichol thanks staff, volunteers and the candidates for all their work during the leadership campaign. "In the leader we place our trust and on their shoulders they carry the hopes of millions in Britain and beyond our borders. It's not to be taken lightly or without a due sense of responsibility," he says, adding: "This party is bigger than any one of us," he says.

The conference kicks off as Labour General Secretary Iain McNichol takes to the stage to address the packed-out room at the QEII conference centre. "Friends, welcome," he begins - "I can tell you that the winner of the leadership contest is...." Hold on a sec...we weren't expecting the result til 11.25? Ah, he stopped the sentence there. What a tease! 

Remember that we will get the deputy leadership result first. Here is one of the candidates, Caroline Flint, arriving a little earlier.

Norman Smith adds that, if he wins, Jeremy Corbyn could soon find himself under pressure - particularly from the parliamentary Labour Party. He says he's spoken to some who think Mr Corbyn could be gone by next summer as they believe it is "untenable" for the party to be led by him.

BBC assistant political editor Norman Smith says he's not spoken to anyone at the conference who expects anything but a Corbyn victory. What is striking, he adds, is the suggestions he may have won in the first ballot. "That would be a phenomenal result, an absolute landslide victory," Norman says. He adds that up to 90% of the new registered supporters could have given their votes to the left-wing MP.

This is the first Labour leadership contest to be fought under the new "one member one vote" system. There is also a new category of so-called registered supporters, who can pay £3 to join. Previously, Labour's electoral college system gave unions, party members and MPs/MEPs a third of the vote each. The changes were brought in by Ed Miliband to reform the party's relationship with the unions, following a row over candidate selection in Falkirk.
