This was the day left-wing MP Jeremy Corbyn became the new leader of the Labour Party- winning the contest by a landslide. It was a remarkable result, given that Mr Corbyn – who has been a backbench MP since 1983 – began the contest as the rank outsider.

He now faces the perhaps unenviable task of putting together a shadow cabinet team – which may not prove easy given that a number of senior figures have ruled out joining his team. As Laura Kuenssberg says, there could be quite a few challenges ahead.

Helping him as he launches what he called the party's "fightback" will be the new deputy leader of the party, Tom Watson - also elected this morning. 

There's been plenty of reaction to Corbyn's win - and if you want an entertaining (and lengthy) read about the new Labour leader's life and times The Jeremy Corbyn Story has been proving popular today

We're ending our rolling coverage for the day now, but you can watch all the key clips via the "key videos" clips on this page - and we'll be back bright and early in time for The Andrew Marr Show on Sunday.

Jeremy Corbyn's win features prominently on the websites of Italy's leading newspapers.

La Stampa says, external "Labour veers left under Jeremy Corbyn, an anti-austerity MP unpopular with the Blairite wing". It highlights his large win, and puts him in a European context as a "pacifist, with similarities to the Syriza and Podemos movements" in Greece and Spain.

Corriere della Sera, external says that after his "crushing victory" he went straight to a "solidarity march for migrants". Left-leaning La Repubblica also leads on his first public appearance, external being a "rally in support of refugees" after beating the other three "establishment" candidates.

Labour MP Richard Burgon says Jeremy Corbyn's style of leadership will be "collective and collegiate" and those who disagree with him on key policies will "get more of a hearing than they did under previous leaders". He urges colleagues to stand "shoulder to shoulder" to take the fight to the Conservatives and does not rule out taking a job in Mr Corbyn's ministerial team.

Angela Smith is the latest to announce she will not continue in a shadow front bench role under Jeremy Corbyn. In a statement on her Facebook page, external, Ms Smith - a shadow food and farming minister, said she had not made the decision "lightly". 

"For my part, the depth of the difference between the views of Jeremy and I on key issues makes it very difficult for me to continue as a member of the front bench. I believe in retaining the UK’s membership of NATO, for instance, and I will campaign for our country to stay within the European Union," she said, and added:

In Spain, papers are making much of Jeremy Corbyn's perceived support for the left-wing anti-austerity Podemos party. "British Pablo Iglesias,"? asks Spain's Libertad Digital., external

The "British Podemos", says El Mundo, detailing the unexpected rise of the Labour candidate. "Corbyn's victory is an earthquake in the history of Labour," says El Periodico, external, noting that "senior party figures see the win as a catastrophe". "It is unclear right now as to who will be willing to work with him. The party is in danger of a split or coming under continuous infighting."

Similarly, under the headline Can Corbyn? (Puede Corbyn?) El Diario, external uses a word pun to draw paralles between Mr Corbyn's success and Spain’s left-wing party named ‘We Can’ (Podemos). But it concedes that "it will not be easy for Corbyn, even with the support of a comfortable majority, to rescue Labour from its neoliberal consensus, with the predictable opposition of the party apparatus and the dense mesh of interests which it shares with the British establishment – to get along with the (other parties of the) very fragmented left".

Finally, for ABC, external, "Corbyn is the closest thing you can find in the UK to Podemos or Syriza". It adds: "He represents a return to the Old Labour of the seventies, which seemed to have fallen by the wayside following the shift to the centre under Tony Blair, who led the socialists to three consecutive absolute majority wins and seemed to have forever changed the face of the party."

Jeremy Corbyn has made it clear he wants to do things differently as Leader of the Opposition and it looks like that also includes his media strategy.

In his first broadcast interview as Labour leader he chose to speak to BBC Radio 1 Newsbeat. His campaign team say he was keen to make it a priority to communicate with younger voters.

For a man who'd just been handed one of the most demanding jobs in politics, he look incredibly relaxed. As he sat in a quiet room away from the television cameras he told the programme:

He also said he believed young people had been "written off" by political parties.
