Labour leadership election as-it-happens

12:20 – OK, on that note, I'm now going to close down the live blog. We'll have blogs and comment up in a jiffy. See you on Monday, when a remarkable new chapter in British politics begins.

12:10 – OK, so this is crucial. Corbyn won among all three groups – members, trade unions and supporters. His mandate is rock solid. His opponents in the party – and there are many – will not be able to get rid of him instantly, as they wished. Couple that with the fact that he clearly reached out to rivals and the stage is set for at least two years of a Corbyn leadership.

12:00 – "The fight back of our party gathers pace." Corbyn, it must be said, is struggling with his delivery.  He points to Khan. "Sadiq, we're going to be campaigning together." Khan doesn't look too pleased with that actually. "This week the Tories will show what they're really made of," he says. He mentions the bill against trade unions and the welfare reform bill. "I want us as a movement to be proud, strong and say we won't pass by those rejected by an unfair welfare system. We're strong enough and big enough and able to do that." He talks about the refugees coming to Europe and says the mood is changing. "They are human beings, just like you, just like me. Let's deal with the refugee crisis with humanity. Going to war creates a legacy of bitterness and problems. Let us be a force for change in the world, a force for peace in the world. We cannot go on like this, with grotesque levels of global inequality. We are one world, let that message go out today from this conference centre. The Tories have used the economic crisis of 2008 to impose a terrible burden on the poorest people in this country. It's not right, it's not necessary and it's got to change. Our party is about justice, it's about democracy. We go forward as a movement and a party, bigger than we've been for a very long time. To show to everyone that the objectives of our party are intact, our passion is intact, our demand for humanity is intact. We're going to reach out to this country so no-one is left on the side. That's what Labour was brought about to achieve, that's what we're going to achieve. Our party will become more inclusive, more involved, more democratic. We're going to shape the future of people in this country. I say thank you to everyone for all their support friendship and comradeship in this election. We don't have to be unequal, it doesn't have to be unfair, things can – and they will – change."

11:57 – Corbyn says his family has been through "the most appaling levels of abuse from the media. It's been wrong. I say to journalists: attack public political figures, but please don't attack people who didn't ask to be put in the limelight. Leave them alone. Leave them alone in all circumstances."

11:56 – You could paint a portrait with the grudging body language of the Labour big beasts, half-clapping as Corbyn praises trade unions.

11:55 – He really is an awful lot like a university professor.

11:54 – Corbyn thanks the 36 MPs who nominated him for the position. "I know some of them had some reluctance to do so, but they did so in a spirit of inclusion and democracy. I look forward to working with all of them."

11:51 – Burnham looks like he's absoutely crest-fallen as Corbyn celebrates his record on the NHS and comprehensive education. Remember Burnham helped get Corbyn on the ballot paper. He dug his grave on this one. Cooper is celebrated for helping to turn around public opinion on refugees. Standing ovation for that. Cooper doesn't look much better than Burnham. Corbyn says one of his first acts as leader will be to go on the march for refugees. He celebrates Kendall for her principles. You do actualy get the sense that the two of them rather grudgingly like one another.

11:47 – Corbyn says the election showed the party and movement were passionate, diverse and united. He thanks Harriet Harman for the time she spent as acting leader. "Her absolute commitment and passion for decency, equality and the rights of women is something we will honour her for. Thank you so much for all you've done." He then thanks and congratulates Tom Watson. "Tom is passionate about communication, passionate about holding unaccountable people to account. Tom is your man to do that." He also thanks Ed Miliband, which gets a surprisingly rousing cheer. "I had a very long conversation with Ed a couple of days ago. I thanked him for his work as leader… and environment secretary. I also thanked him for the way in which he stood up to the abuse he recieved by much of our media." That's your first media attack right there. He cites his resistence over the Ralph Miliband story – a sign he plans to try to take on the media in the same way.

11:45 – Here comes his speech. Extraordinary scenes. He can't calm down the room. 

11:44 – Here are the full scores – Corbyn: 251,417 (59.5%) Burnham: 80,462 (19%) Cooper: 71,928 (17%) Kendall: 18,857 (4.5%)

11:42 – Corbyn has won in the first round with a whopping 59% of the vote.

11:41 – Ok, here we go. The leadership results.

11:38 – "This election has been as much a referendum on the political culture of the Labour party as it has been about the candidates' policies. Even our own people are sick of the old ways of doing politics. Let the Tories and the pundits think we're weak while we unleash the implacable power of hope. To those Tories sniggering that we won't win in 2020 I say this: Watch this space. Watch your backs. We will win in 2020. To my comrades in arms, I say come with us, join with us. There should be nowhere in these islands which is not Labour."

11:33 – Watson thanks the National Union of Mine Workers. "I gave you my solidarity as a five year old [during the 78 miners strike], so thank you for giving it back to me." "I plan to back our leader 100%. I ask you to be the same. Only through unity comes strength. Labour is the last line of defence for the millions of people who ssuffer in their hands. To those who feel alarmed by the scale of difference between the old world and the new I say this: There is only one Labour. We are the guardians of decency and fairness, justice and equality in the United Kingdom and we're going to continue to do that. At our best we articulate and embody the common sense and compassion of the British people. This has never been a fair country. The Tories don't play fair. Their markets are arbitrary and unforgiving. Anyone who thinks there's a contradiction between pro-business and pro-worker doesn't understand either."

11:31 – He goes up to make a speech. Remarkable moment, only seeming less so because something even more remarkable is about to happen. He's gone from Brownite enforcer, to phone-hacker campaigner, to this. Once he was a figure of division, even a symbol of it. Now he'll try to be a uniter, keeping the party's right and centre on board under Corbyn.

11:31 – Tom Watson is the deputy leader of the Labour party. 

11:29 – Eagle eliminated. Round three – Creasy: 26.4% Flint: 22.8% Watson: 50.7%

11:28 – Bradshaw eliminated. Round two –  Creasy: 21.4% Eagle: 17.9% Flint: 18.4% Watson: 42.2%

11:25 – First round scores: Bradshaw: 5.6% Creasy: 19.1% Eagle: 16.2% Flint: 15.8% Watson: 39.4%

11:24 – Here we go. There's a remarkable scene as cameramen just horde around the candidates, right in their face on the first row. They smile akwardly. 

11:22 – The deputy leadership candidates are up on stage. Most of them are smiling. 

11:21 – "Let's rally together because together we can make a difference and change this city and this country," he ends.

11:19 – Khan says winning London next year will be a huge challenge. We need to show we're in tune wth the British people, that we understand the challenges they face." Khan says opportunity allowed his parents to move to the UK, and gave them a council house, from where they could build for the future. "Whatever happens we must pull together."

11:17 – "I still can't quite believe I'm standing here as your candidate for mayor of London," he says. " I never believed that me, a south London boy, son of immigrants, who grew up on a council estate, could be standing here today."

11:16 – Sadiq Khan, who was selected yesterday as Labour's London mayoral candidate, is up to speak now.

11:12 – "Isn't it remarkable that so many people have joined Labour? I welcome them all." I'm not sure he's been entirely consistent. "I look forward to seeing them on the doorstep with members who have campaigned for years and decades." You get a hint of the seething anger amid some long-term members and officials there that they have been overwhelmed by people who don't even vote for Labour.

11:08 – OK, the speeches have begun, starting with the Labour general secretary. Seriously weird tone. "We've weeded out those who have cynically tried to subvert our democracy. We've run a free and fair election." Like a Stalinist rally.

11:07 – There are even reports – this really would be remarkable – that he may have won on over 60% of first preference votes.

11:00 –  Then we'll get the leadership announcement. Corbyn could win in the first round if he won more than 50% of first preference votes. That's actually likely. If not, we'll knock out the candidates from the bottom to the top, with their second preference votes being redistributed. In all likelihood, it'll be Liz Kendall knocked out first, then, given reports of a late surge for Yvette Cooper, it'll be Andy Burnham. And then Cooper in second place. Kendall's supporters are unlikely to have lent their support to Corbyn, so if it goes this way, it'll likely take until Burnham is knocked out for Corbyn to cross the line. 

10:57 – Very soon we'll be getting the deputy leadership results. This has been mostly overshadowed, but the candidates, roughly in order of expectation, are: Tom Watson, Stella Creasy, Caroline Flint, Angela Eagle and Ben Bradshaw. Watson will probably get it – but major health warning on that. Despite all the certainty around Corbyn, there haven't actually been that many opinion polls during the contest. 

10:36 – Whoever wins, they won't lack a mandate. Turnout was 76.3%. There's a total electorate of 553,954 members, affiliated trade union members and £3 supporters, meaning 423,000 people voted. That compares to 198,844 in the last Conservative leadership contest and 33,897 in the last Lib Dem one.

10:27 – Good morning and welcome to what is likely to be one of the most extraordinary days in British politics for a very long time. After an interminable, seemingly endless, campaign, today we get to find out who will be the next leader and deputy leader of the Labour party. We all expect it to be Jeremy Corbyn and for an unprecedented moment to have arrived, in which Labour veers drastically to the left. Could this be the the beginning of the end for the centrist focus in British politics, which has lasted over 30 years? Or simply the beginning of the end for the Labour party? One thing's certain: we're in uncharted water.
