So Jeremy Corbyn has been re-elected as Labour's leader with a larger mandate than a year ago.

There was plenty of talk from the leader and his supporters ahead of the result of "coming together" after a second bruising campaign.

He even provided proof on BBC TV that he was growing a diminutive olive tree outside his office - the presumed purpose of which is to break off a branch and proffer it to his internal opponents.

But some of the MPs who voted for a motion of no confidence in him believe that those around the leader will only sue for peace on their terms.

A senior Welsh Labour MP says she is willing to serve under Jeremy Corbyn again, three months after quitting the shadow cabinet.

Jeremy Corbyn speaks to the party conference after he wins a second Labour leadership contest.

He paid tribute to his rival Owen Smith and then told delegates that they "have much more in common than that which divides us".

And he went on to say: "Let's wipe that slate clean, from today, and get on with the work we have got to do as a party together."

The 2016 Labour leadership campaign saw more "very hurtful and unpleasant allegations " and was nastier than the vote 12 months ago, said Diane Abbott.

The shadow health secretary told BBC assistant political editor Norman Smith that "no-one close to Jeremy is talking about deselections and purges".

She appealed for the party to come together, and said there was no wish for a "purge" after Mr Corbyn was re-elected with nearly 62% of the vote.

How the Labour result was announced, with the speech of re-elected leader Jeremy Corbyn.

Chuka Umunna reacts to Jeremy Corbyn's re-election as leader of the Labour Party.

Shadow Chancellor John McDonnell says he thinks the Conservatives will call an early election.

The Green Party's joint leaders have called on Jeremy Corbyn to make a pact to beat the Conservatives.

"It’s absolutely crucial that those of us on the progressive side of politics work together to best oppose what the Conservatives are doing to Britain," says co-leader Jonathan Bartley.

MP Caroline Lucas, who is joint leader in a job share with Mr Bartley, said:

The CBI has said it looks forward to working with Jeremy Corbyn and calls for "partnership" between business and politicians.

"We congratulate Mr Corbyn on his re-election as leader of the Labour Party, and look forward to continuing to work with him and his team," said director general Carolyn Fairbairn.

"It's critical that the country has a strong opposition at a pivotal moment in our nation's history.

"Now is the time for an unprecedented partnership between business and politicians of all parties to drive growth, create jobs and spread prosperity across the country.

"Firms will want to see Mr Corbyn and his team throw their weight behind measures including ensuring young people are given the right skills to succeed in the workplace, improving the infrastructure links connecting our regions and building more affordable housing."

Liberal Democrat leader Tim Farron says Jeremy Corbyn's re-election means that Labour "continues to be dominated by ineffectual leaders".

Mr Farron, who tried to appeal to Labour voters in his recent conference speech, has written for Labour-leaning website Left Foot Forward, calling for "moderate progressives to work together and fight for what we believe in".

Owen Smith has said he is "proud and privileged to have stood to lead our party and to have won the support of 193,000 members and supporters".

The defeated challenger said he respects the result and will consider "what role I might play in future to help Labour win again".

And he added:

Patrick McLoughlin, the chairman of the Conservative Party, responds to Jeremy Corbyn's re-election.

He tells the BBC that "172 [Labour] members of Parliament don’t think he is competent enough to run his party" and adds:

Labour's John McDonnell predicts that Theresa May will go for an early general election.

"The Tories are ripping themselves apart over Brexit," he says.

He adds that the referendum decision to leave the EU must be respected.

Shadow chancellor John McDonnell says Labour MPs have nothing to fear and there is no threat of deselection.

He declines to commit to shadow cabinet elections, saying there needs to be further discussions.

And he says that a number of MPs have approached him privately about returning to the front bench.

Would an invitation to return extend to Hilary Benn, whose departure as shadow foreign secretary in June sparked a wider shadow cabinet walkout?

Mr McDonnell says yes.

It's worth putting today's victory in historic context. Before 2015, the Labour left had never won a leadership election in the Labour Party. As of today it's won twice in just over a year. Even in Tony Benn's heyday, he couldn't quite manage to defeat Denis Healey for the deputy leadership. The Labour Party has always been controlled essentially by an exchange between the party's right and soft left, to varying degrees of success. Power between left and right was shared across the different institutions of the party.

Today virtually every organ of Labour: the trade unions, the NEC, the leadership, the membership are scions of the Left. The only redoubt of moderate strength are the MPs, and if today proves anything, it's how little they matter.

Jeremy Corbyn and his team has totally bypassed them. In its 116 year history, the Labour left has never been more powerful. Like it or not, it's a party transformed.

Shadow health secretary Diane Abbott, a Corbyn supporter, echoes the leader's words about wiping the slate clean.

"We're not going to hold anything said in the campaign against anybody," she says.

"We want the party to unite."
