Live updates: Labour turmoil continues

Labour leadership challenger Owen Smith has said he will withdraw from the contest if Angela Eagle - who has also launched a bid to replace Jeremy Corbyn - secures more support from colleagues.

Mr Smith told ITV News: "I don't think that the person who doesn't command majority support in the PLP (Parliamentary Labour Party) can credibly say they are the unity candidate."

He added: "And I think the most important thing is uniting the Labour Party, we're in danger of splitting...that's why I'm standing in this contest."

Angela Eagle has urged Labour supporters to "save" the party, and "heal" the country by signing up to remove leader Jeremy Corbyn.

Ms Eagle has pleaded with opponents of Mr Corbyn to pay the increased £25 fee to challenge his leadership.

Speaking to the BBC, she said: "I would say to the nine million Labour voters out there, there's two days next week when you can actually pay £25, help save the Labour Party, make our democracy work and help me heal our country. Join as a registered supporter.

"Join us in this battle, let us win the Labour Party back", she added.

Ms Eagle also said the membership fee was "pretty good investment for the whole future of democracy".

Jeremy Corbyn addressed thousands of supporters in London after finding out his name will be on the ballot paper in Labour's leadership contest.

Corbyn arrived at a fundraising event at the O2 Forum in Kentish Town, north London, on Tuesday evening, after a meeting with the party's ruling committee.

Supporters said Mr Corbyn was defiant and spoke about the upcoming party election.

Andy Gregg, from St Albans, said: "He reaffirmed our faith in the fact that change is possible. He astonished me by how resilient from the attacks from the establishment he was."

Jeremy Corbyn won a big victory tonight in his fight to stay on as Labour leader.

The party's ruling national executive voted in favour of his name being put on the ballot paper automatically.

Earlier in the day, Mr Corbyn revealed he had received death threats in the last few days and his challenger Angela Eagle had a brick thrown through her office overnight.

Our Political Correspondent Carl Dinnen reports:

The result of the Labour leadership contest will be announced at a special conference on Saturday 24 September.

The hustings period opens on Friday 22 July and runs until Friday 16 September.

A further timetable of activities will be published on Thursday.

People who joined Labour after February this year will not be allowed to vote in the party's leadership contest, the National Executive Committee (NEC) has ruled.

The freeze date for party members eligible to vote was agreed by the NEC as six months. It means people who signed up recently have been frozen out.

The committee also has agreed that Register Supporters who signed up for the last Labour leadership election will have to sign up again and pay £25 to vote.

They have a 48-hour period from Thursday to Saturday to join and pay the one-off £25 to vote in the contest.
