Labour leadership challenger Owen Smith's campaign team will include MPs Kate Green MP, Heidi Alexander, Lisa Nandy and Jo Stevens as well as Neale Coleman, a former aide to Jeremy Corbyn - who will become Mr Smith's chief policy adviser and John Lehal, who will be chief of operations.

Mr Smith said: "I'm proud to have assembled a strong, radical senior team to help me flesh out a vision for Labour's future. 

"I served loyally in the shadow cabinet alongside Kate, Heidi and Lisa, and witnessed first hand that they are some of the finest members of the new generation of leaders in the Labour Party. 

"I'm also delighted that Neale Coleman has agreed to come on board as my chief policy adviser. He has a wealth of expertise, including working across major projects in City Hall, where he helped deliver the 2012 Olympics."

Members of the British-Irish Council have called for any future Brexit deal to be ratified by all four UK parliaments.

The impact of leaving the EU was discussed at an extraordinary summit in Cardiff, where representatives of Scotland, Wales and Northern Ireland voiced their concern at potentially being "done over" by the UK government, when Brexit negotiations begin.

The prime minister's pledge to involve different administrations was welcomed, but there was a call to ensure that would mean different governments have a "seat at the table."

Concerns were also raised over the prospect of new border controls being introduced between Northern Ireland and the Republic - with the Irish Taoiseach insisting they cannot return to the days of border posts and watchtowers.

On the row over whether Labour Leader Jeremy Corbyn is doing enough to combat abuse directed at his MPs, his close ally - the shadow chancellor John McDonnell has told the BBC he has "been moving Heaven and earth" to say abuse is not acceptable.

"I think he's really worked hard on that, I just think that Owen Smith and others should stop attacking Jeremy personally." 

He told the BBC, abuse goes both ways - and criticised leadership challenger Mr Smith for comparing Mr Corbyn's practices to those of under-fire retailer Sports Direct:

Philip Hammond is simply giving himself some "wriggle room" ahead of the Autumn Statement, in hinting that there could be a shift in economic policy, says the man who was chief of staff to his predecessor.

Rupert Harrison said the new chancellor's approach wasn't too different to George Osborne's, as he had warned that certain economic targets would be difficult to meet.

"There's a trigger in the existing arrangements that if growth is forecast to be below 1% then the surplus target is put to the right and suspended and I would think that's very likely to happen.

New UK Chancellor Philip Hammond has played down a closely-watched survey of business managers, which suggested that there was a sharp fall in business activity since the Brext vote.

The survey of purchasing managers, by Markit, pushed sterling down by more than a cent against the dollar.

Mr Hammond, on a visit to China, said: "Let's be clear, the PMI data is a measure of sentiment, it's not a measure of any hard activity in the economy.

"What it tells us is business confidence has been dented, they're not sure, they're in a period of uncertainty now."

Paul Johnson, the director of the Institute for Fiscal Studies, has been telling the BBC what he thinks a fiscal "reset" - as mentioned by the UK chancellor in Beijing - might mean:  

"I take as meaning he will want to think through what he wants to do in terms of tax and spending precisely in the context of expecting the economic news come the autumn, come the Autumn Statement, to be significantly worse than it looked back in March when the current set of policies were made," he said.

He also it was "nonsense" to suggest the chancellor was "talking down the economy" but added that it was too early to say how the economy was performing since the EU Referendum:

Shadow Chancellor John McDonnell says Philip Hammond should fly back to the UK from China to change the government's economic policy to allow more investment.

The chancellor has signalled that he may use the Autumn statement to "reset" fiscal policy if needed - the prime minister has already said the government would no longer seek to reach a surplus by 2020. 

Mr McDonnell said the UK could not wait that long: "He needs to get back here now, government departments are operating under a rule that clearly even he now accepts isn't workable."

He said waiting until autumn would hold back investment: "This is the time to invest... if you borrow when borrowing is cheap, as it is now, it pays for itself by growing the economy."

Labour leadership challenger Owen Smith has accused Jeremy Corbyn of effectively licensing abuse of his critics by his supporters.

It follows claims by Labour MP Angela Eagle, who has stopped her constituency surgeries over safety fears, that Mr Corbyn had "stirred" things up.

Mr Corbyn says he has spoken out against harassment and threats and has been on the receiving end himself - but Mr Smith told the BBC that "this sort of abuse" had not been in the party before Mr Corbyn became leader. 

Labour says the British economy is effectively "on hold" over the summer after Chancellor Philip Hammond hinted at a possible "reset" of the government's fiscal policy in response to any Brexit-related showdown.

Shadow chancellor John McDonnell said the Conservatives had "no plan" for what would happen after a vote to leave the EU and were "now making it up" as they go along.

But a former adviser to George Osborne says talk of accelerating infrastructure projects is a bit of a misnomer.

Rupert Harrison, who now works in the City, tells Radio 4's World at One that this isn't 1930s America and you can't simply drum up a group of men to dig up a road or build a railway in order to provide an immediate economic stimulus.

What is holding up infrastructure projects, he says, is not shortage of investment but the simple lack of capacity to take them forward.

While Mr Hammond is right not to rule out action in the future if there is hard evidence of a weakening economy, he says monetary policy should be the "first line of defence" and he would expect the Bank of England, not the Treasury, to be the ones to react first - that's a reference to a possible interest rate cut.

Jeremy Vine went straight into a record after his Jeremy Corbyn interview, which happened to be the Billy Ocean classic Red Light (Spells Danger). Who is in charge of the Radio 2 playlist, I wonder?

Apparently Mr Corbyn on his way out has been talking to Mr Vine's next guest - the rapper Professor Green. 

BBC Radio 2

Mr Corbyn urges Labour to "come together" and provide a "real economic alternative and real hope for people of this country".

He says "something exciting" is happening in British politics, citing the 500,000 people that have joined the party since he became leader

"That is not to be sneered or sneezed at".

He goes onto to reject comparisons between his kind of political insurgency and that of Donald Trump, saying he is not confident that the Republican president candidate will win and he has more in common with the Democrat politician and former candidate Bernie Sanders.

He describes Mr Trump's approach to international affairs is "beyond strange" saying his election will result in the US becoming "totally isolated" - stressing that this has never worked in the past and UK-US relations will remain strong whatever.

Jeremy Corbyn is asked about claims that dissident MPs could be de-selected when the new Parliamentary boundaries are drawn in 2018.

He says sitting MPs will be "automatically shortlisted" and then it will be up to party members to decide whether to confirm them or move to an "open selection" - suggesting activists are the "employer and the boss" not him.

He rejects claims that critical MPs could be turfed out by supporters of the Momentum campaign group, saying Momentum is not "big enough to stack" every local constituency party.

He goes onto to say he hopes that people aren't talking about the party splitting - saying Labour is the party that has stood up for working people for 100 years.

Jeremy Corbyn says he is "human" and where he makes mistakes he is prepared to "fess up".

He says he has apologised to Labour MP Thangam Debbonaire about the way she was handled when she was asked to join his ministerial team last year. 

She has claimed she was appointed shadow arts minister without being told - and while she was receiving cancer treatment - and was almost immediately sacked, when part of her brief was given away. 

Mr Corbyn says this isn't strictly correct but says that she is talented MP who he hopes can make a real contribution to arts policy in the future.

Asked about dissent in his parliamentary party, Mr Corbyn says some MPs are "more hostile than others" and praises newly promoted shadow cabinet ministers for stepping up and doing a great job in recent weeks.

He says Labour MPs have a "responsibility to the communities that elect them" but also to provide the best opposition to the government.

If he wins re-election, he pledges to construct a "broad, diverse" shadow cabinet that represents as many different strands of opinion.

The Labour leader says he is "well prepared" for the leadership fight ahead.

Jeremy Corbyn is making what I think is his first appearance for a while, if ever, on the Jeremy Vine show on Radio 2. When this show was hosted by Jimmy Young many years ago - it was one of Mrs Thatcher's interview spots. 

When Mr Vine suggests Mr Corbyn is "having a time of it", he express a bit of surprise, saying he is "happy and fine".

Elaborating, he says he is "eating normally", doing plenty of exercise, reading subjects outside of politics and enjoys listening and talking to people.

Asked whether he can win a general election, he says there won't be one for a while and rejects suggestions that just because he is from Islington that does not mean he can't "reach out" to people from outside London.

Neale Coleman who was until recently part of Jeremy Corbyn's leadership campaign team has agreed to advise Owen Smith.    

Bookmaker William Hill does not rate Owen Smith's chances of unseating Jeremy Corbyn for the Labour leadership.

The odds they are offering - 1/7 suggest Mr Corbyn will win by a landslide. They are offering 7/1 that Mr Smith will concede defeat and withdraw from the race. 

 "As it stands, the leadership race looks very one-sided and there has to be a chance that Mr Smith decides to concede defeat," said William Hill spokesman Rupert Adams. 

Has Labour leader Jeremy Corbyn performed a U-turn on whether Article 50 should be triggered straightaway?
