Just replacing one leader with another without proper analysis isn’t going to get Labour very far, Mr Johnson says. He adds it is possible that Labour is still fighting over the old Blairite/Brownite battle lines.

"You would think that Tony Blair lost us three elections not won us three elections," he says.That’s a fundamental flaw.

"David Cameron had to prove that we would fail in government. If we’re helping him by suggesting that we failed in our 13 years in government, then that’s not going to do us any good," Mr Johnson says.

Alan Johnson tells the Today programme Labour lost the argument on the economy, saying it couldn’t properly counter the myth over Labour’s recession. He says the party would have “borrowed to invest with interest rates at near-zero” so there was a big dividing line between themselves and the Tories.

“It is much more fundamental than just changing the leadership,” he says.

“Ed Miliband is a decent man, he fought a decent campaign, but there is a fundamental issue here,” he adds.

He says David Cameron won an overall majority at a time when people are seriously worried about poverty and about whether their kids will have a better future than they have. "We didn’t grasp that, despite Ed’s best effort to make that an issue. That’s an issue globally, never mind just in this country. That never got translated into aspiration for people’s lives."

Former Labour cabinet minister Alan Johnson tells the Today programme he isn’t interested in becoming leader of his party.

He says: “No, I don’t have the qualities. This is a ten year task”

He says the party faces a deeper problem than just whether Ed Miliband was leader or how he ate a bacon sandwich.

He questions why Labour lost seats like Hastings, Thanet, Bury. He says the Labour party is no longer the party of “aspiration”.

“We can no longer relate to [people] as a party of aspiration,” he says. He claims this was why New Labour won three elections in the past.

John Denham, Ed Miliband's former parliamentary private secretary, says that Labour came across as being economically radical to the electorate, but didn't clearly explain how their policies would make a difference to the country.

Mr Montgomerie says Mr Cameron faces a genuine problem, despite achieving a majority that few commentators including himself predicted, in that he has a group of potentially rebellious backbench MPs.

Mr Cameron must try to avoid this parliament being as fractured and divided as it was after 1992 under John Major, he says, who, he points out, had a larger majority than the prime minister enjoys.

The things that go in his favour are the fact that a number of MPs owe their seats to the fact that Mr Cameron is the first prime minister to increase their majority since 1983.

But at the same time there may be quite a few independently minded rebellious MPs who are there to stand up for what they believe in. "We just don’t know how many of them there are," he adds.

The last parliament was “the most rebellious of the post war period” Mr Montgomerie tells Today. “You had more rebels against David Cameron on Europe, on constitutional issues, on tax,” he says.

Mr Montgomerie adds Mr Cameron had a large majority last time - with the help of the Lib Dems - and those MPs that did rebel from his own party felt they had licence to do so because the prime minister was defending the coalition agreement, while his backbenchers felt that they were the guardians of the Tory manifesto.

He says: “Once you get into that mindset of rebellion can you suddenly become loyal and disciplined in this parliament?”

“The trouble starts now says,” Mr Montgomerie says.

Labour did not "land the message" they wanted to get across to the electorate on the economy, Ed Miliband's former parliamentary private secretary John Denham tells Radio 5 live. "A lot of the election was decided north and south of the border by a sense of national community and identity," he adds.

Being a special adviser to a minister was a disadvantage in the last round of recruitment for Conservative MPs, Tim Montgomerie, columnist at the Times, tells the Today programme.

He says much of the new intake of MPs are very independently minded, lawyers, business people and so on.

But the new intake reinforces the same old Tory problem, that its MPs are not particularly representative of the population.

Mr Montgomerie says that they are well-off, nearly all married, nearly all from professional backgrounds, university educated, ex-City -  only one new MP on the list he has seen has come from the public sector.

He says it makes the party look like the party of the rich, the party that has already made it. “It still has some way to go to get northern candidates…from poorer working class backgrounds," he adds.

Sir Menzies Campbell told BBC Breakfast that the Lib Dems did not successfully highlight what they had done in government to the electorate.

"We did not get the credit which we deserve - this is not a plaintive cry, it's the truth - we did not get the credit we deserve, for, almost exactly five years ago, going into coalition with the Conservatives in the national interest, because of the state the economy was in."

Sir Menzies Campbell, a former leader of the Lib Dems, tells BBC Breakfast the party was "punished" at the polls.

He added that the Lib Dems now have to go back and re-establish themselves in local government, and off the back of that, try to get parliamentary success.

Labour and the Conservatives were portrayed in the polls as being neck and neck, with other parties predicted to hold the balance of power. But as it turned out, the Conservatives gained a majority. Former pollster Ben Shimson of the Britain Thinks research group is asked: How did the pollsters get it so wrong?

SNP leader Nicola Sturgeon will be meeting up with her new Westminster intake today with 56 SNP MPs preparing to take seats at the House of Commons. But how difficult can they make life for the Conservatives? Scotland correspondent Laura Bicker says: "This is where David Cameron's majority comes into play. In theory he can get through whatever he wants to get through... [but the SNP] can make their voices heard from the opposition benches, and they can put a lot of pressure on the Conservatives."

Professor Charlie Jeffrey of the University of Edinburgh said the Scottish National Party's (SNP) almost total victory in Scotland yesterday was "extraordinary" and "record breaking in practically every respect."

He said there are a number of reasons that the SNP did so well, including gains made in traditional areas during the Scottish referendum, a "very effective leadership change" from Alex Salmond to Nicola Sturgeon, and an emphasis on social justice that attracted Labour voters.

Green Party leader Natalie Bennett has said she'll stay on, despite not managing to win a seat. The Greens boosted their share of the vote to just under 4%. "In terms of the seat I was standing in, Holborn and St Pancras, I always made it clear that I had a huge mountain to climb. I stood in the seat where I live... where I've been a community campaigner - that was the right place for me to stand. But for the Green Party, despite our concern about the overall result, this was an excellent election. We got four times more votes in a general election than we've ever got before. 1.1 million people."
