Laura Sandys says that while the UK could continue to trade with the EU, even if it was not a member, "we would not be setting the rules". It would take 10 years to get the agreements in place, too, she adds.

Philip Davies says the UK does not have as much influence as has been suggested. "More often or not we're outvoted," he adds.

Should the UK stay or leave the EU? That's the subject under discussion now, with Tory Eurosceptic Philip Davies and Europe Movement chairwoman Laura Sandys, a former Conservative MP.

Ms Sandys says to leave the EU, "the largest market in the world", would be "very foolish". But Mr Davies says a "Brexit" is the only way the UK can control its borders. He also argues that future growth in the world economy is not going to emanate from Europe, making the case that the UK would be fine if it left the EU.

Chris Leslie says the banking crisis was the cause of the financial crash, but says the Tories successfully made out it was down to too high levels of spending.

"Could we have spent less, yes we could have done. Could we and should we have braced ourselves more, yes we should have done," he tells the Sunday Politics programme.

Labour now has to "prove to the public that living within our means is in our soul, and part of our DNA", he adds.

Asked about the previous Labour government's economic record, and if he thinks it borrowed too much before the crash, Chris Leslie says "hindsight is a wonderful thing", adding that the UK could have been better braced for it.

"But there was a consensus at the time that the levels of public expenditure were the right ones, including from George Osborne."

Chris Leslie is asked whether Labour will press ahead with plans for a mansion tax. "We don't have a policy on it at the moment", as everything is up for review, he says.

What about the 50p tax rate, is that off the table? All of our policies are up for review, he restates. The shadow chancellor says he suspects George Osborne is "toying" with whether to cut the top rate of income tax from 45p to 40p, something he says he would not support.

"I don't think we were anti-business but we didn't deal with that accusation strongly enough," says Chris Leslie.

Was there tension within the top team about attitudes to business? He says there was a discussion about how the party rebutted the "false accusation" that it was anti-business, but reiterates that Labour didn't do enough.

Chris Leslie says he thinks the party didn't successfully communicate its economic message. Labour also allowed its opponents to "mis-characterise" our attitude towards business and the economy, he adds.

The shadow chancellor says he's backing Yvette Cooper for the party leadership, endorsing her approach to business.

Shadow chancellor Chris Leslie says there are some "very strong candidates" in the field for the Labour leadership. He says it's important the party reflects on why it lost the election and learns the lessons.

Asked about Andy Burnham's candidacy, in particular his comments that the 2015 manifesto was the best he's ever fought on, he says Andrew Neil will have to ask Mr Burnham about that. Mr Leslie adds that for him the best manifestos are the ones that convince the public.

Time now for BBC One's Sunday Politics.On the  programme today are shadow chancellor Chris Leslie, Conservative Eurosceptic MP Chris Leslie and former Tory MP Laura Sandys, who chairs the European Movement.

 On the upcoming EU referendum, Alex Salmond says people are right to be "extraordinarily concerned" by the government's attempts to remove the purdah period. He also restates his opposition to the referendum being held on the same day as any other elections. He says the government shouldn't try to use the civil service machine during the campaign to "bias the referendum".  

Alex Salmond, the SNP's foreign affairs spokesman, dismisses reports he's seeking a place on the parliamentary Intelligence and Security Committee. "I don't think I want to spend a huge amount of my time monitoring the activities of spooks," he says, but adds that an SNP member will be on it.

But Guardian columnist Zoe Williams challenges his remarks, suggesting they were rude. Alex Salmond responds by saying she must know "very little" about Scottish idioms - which doesn't go down well.

A frank exchange of words ensues, and John Pienaar tries to intervene. But Mr Salmond presses on, saying that with the "greatest respect", Nicola Sturgeon knows him better. He also suggests Ms Williams is "trying to be entertaining" but "you're definitely not being". Round two! This time Pienaar manages to move it on.

Up next on Pienaar's Politics is Alex Salmond, SNP MP. He's asked about the claims that he's sexist, after he told Defence Minister Anna Soubry to "behave yourself, woman".

He says he agrees with Nicola Sturgeon, who said in his defence that he is "the least sexist man she knows". He says he doesn't have "a sexist bone in my body".

Stella Creasy, MP for Walthamstow, says Labour needs to improve the way it works with its grassroots "and that's why I'm standing".

She says there was "no one truth" which explained the election result, saying there were "eight seats where 2,500 votes a different way" would have stopped the Conservatives having a majority. But in others seats, Labour lost MPs such as Ed Balls.

Asked about Labour's election defeat, Stella Creasy - who is vying for the deputy leadership - says it was "a gut punch". Labour "fought to win" but ultimately it was "a comprehensive defeat", she says.

She says the election showed that the way the party campaigns and connects with the electorate needs to change.

In response to a question on defence spending, with the government under pressure to commit to spending at least 2% of GDP on defence, Labour MP Stella Creasy says it's not just about the UK but its relationship with other countries, noting that the 2% target is set by Nato.
