Natalie Bennett is keen to draw distinctions between the Green Party's "long term vision for Britain" and their manifesto for this election. In the long run, they want to spend far, far less on defence and boost aid to 1% of GDP - she says improving the lives of people around the world would make the UK more secure than buying more nuclear weapons.

How can you afford to be so completely against austerity, the Green leader is asked. Multinational companies and rich individuals aren't paying their way, she replies, so the Greens would raise £20bn from a Robin Hood tax, for example. "We're not afraid to say they have to pay more." UKIP says concerns over low wages and crowded schools are down to immigration, argues Ms Bennett, when in fact they are down to poor planning and a failure to spend government resources in the right way.

"I'm a human being, we have failings, I'm not a spin machine," says Natalie Bennett when she's asked about That Interview on LBC a few weeks ago. She says it's now time to move on.

We'll be hearing more from Defence Secretary Michael Fallon in the Commons a bit later on UK efforts to "beef up" the defence of the Falklands, as he put it. But in the meantime, our colleague has pulled together what we know so far. Read it here.

Here's a selection of the comments we've been receiving on David Cameron's third term announcement - they're all very supportive of the prime minister...

To me this was a sensible remark, provided it was on the basis he had won a second term in the first place! It provides clarity.

Richard Hall

There is no doubt that both Margaret Thatcher and Tony Blair overstayed their time in office. Their earlier performances in the first two terms of their respective offices in power far exceeded poor performances from them both in a final term of office - many complex problems were caused by them hanging on and caused considerable difficulties for their cabinet members and successors!

Gerry Dingley

No sensible person, or politician, should want to serve more than 10 years in office. So my vote goes to Cameron on this for taking an entirely pragmatic approach.

David Trevers

I don't see why the Lib Dem and Labour counterparts have anything against the Prime Minister making an honest, hypothetical and decent statement. He is simply stating he isn't egotistical... his goal is to fix the economy - hopefully he will. Thanks Prime Minister!

Boris Johnson wraps up his hour answering listeners' questions on LBC by elaborating on his opposition to a third runway at Heathrow. "If you continue with the expansion of Heathrow you will see environmental devastation across London," he says. There would be 320,000 people affected by serious noise pollution and west London would be "choked with traffic".

Here's what Danny Alexander, the Liberal Democrat Chief Secretary to the Treasury, has to say about today's inflation figures falling to zero: "Today's zero inflation is the right sort of price freeze, with low oil prices feeding through to prices. Coming alongside good growth and record numbers of jobs, Liberal Democrats in government are delivering a stronger economy and a fairer society. It's yet another month that sees earnings pulling ahead of prices, which will be a great help to millions of families."

Boris Johnson delivers a potted history of Winston Churchill's views on defence spending, pointing out that while he was a "great re-militariser" in the 1930s, he had argued for defence cuts in the first decade of the 20th Century. It's in response to a listener who's disappointed that the Conservatives aren't backing the armed forces. "The Conservative Party is utterly committed to a strong defence, to standing up to Russian revanchism in eastern Europe," he says. Revanchism - for those of you, like us, who are not on Boris's verbal level - apparently means a policy of seeking to retaliate. to reverse territorial losses incurred by a country.

The London Mayor paints a vivid picture of his nocturnal activities in his office. Sitting there late at night "meditating great thoughts for London", Boris Johnson says, he often gets interrupted by the energy-saving system which automatically switches the lights off if no motion is detected. "I have to jump up and down and wave my arms to bring them back on," he says.

Boris Johnson is pressed on how he felt about being named as one of three possible leadership contenders. "Of all the subjects in the world this is the one that sends me into the deepest coma of tedium," he says, before wriggling uncomfortably for several minutes. Here are some of the comments he had to say:

• "I felt very pleased that the prime minister is going to go on for five years."

• "There are many candidates out there."

• "To be perfectly honest I don't think the prime minister has actually said anything new. I don't want to sound dementedly conceited about it, but I think he has said stuff like this before."

• "This is a hypothetical question - there is no vacancy, nor will there be a vacancy for five years which is an incredibly long time. We're talking about 2020."

• Will he go for it? "I can't possibly answer that because it is a long way off."

The high stakes of this year's general election will result in turmoil among the party leaderships, Rachel Sylvester writes in the Times, external. She imagines a "bloodbath" and offers readers the chance to play "political Cluedo" by working out what "Westminster deaths" might be in the offing. Nigel Farage as Professor Plum, Nick Clegg as Colonel Mustard - and then there's the Labour leader. "Ed Miliband is an unlikely Miss Scarlett..."

Boris Johnson is answering a question about Grant Shapps' second job while working as an MP. The Conservative Party chairman told "porky pies", a listener suggests, but the London mayor disagrees. "If there was an overlap it wasn't very long. People are bashing this guy because he was so enterprising," he says. But what about the fact that Mr Shapps said he hadn't had a second job at all. Mr Johnson says he's sure Mr Shapps "forgot" rather than sought to deliberately mislead.
