Why it is absurd for Cameron to claim that he and Cable are united

The PM and the Business Secretary are making diametrically opposed arguments on borrowing for growth.

There is no need to have "a fight" with Vince Cable because there is nothing to have a fight about. That was the argument David Cameron sought to make during the Q&A following his speech on the economy. He pointed out that Cable's New Statesman essay had been signed off by the Treasury (a decision Team Osborne may well now regret) and insisted that the Business Secretary was in full agreement with the government's economic policy. 

But as a close reading of both texts shows, the Prime Minister and the Business Secretary are making diametrically opposed arguments on borrowing for growth. Here are three key points of difference. 

Where Cameron and Cable disagree

1. Would higher borrowing threaten economic stability?

Cameron claimed that deficit-financed stimulus would "jeopardise" the nation’s finances by triggering a spike in interest rates. Cable said the reverse. Highlighting the long-term maturity of the UK's debt, he wrote that "we suffer less from the risks of a debt spiral, where refinancing maturing debt rapidly becomes impossible. Consequently, the effect on our fiscal situation of higher interest rates is in fact nowhere near as bad as having weak growth". 

2. Can borrowing for growth aid deficit reduction?

In his speech, Cameron ridiculed those who think "borrowing more money would mean borrowing less". But in his NS essay, Cable argued that borrowing to invest would not "undermine the central objective of reducing the structural deficit" (a measure that excludes capital spending) and could even assist it "by by reviving growth".

3. Can the government afford to spend more?

Cameron argued that was there no "magic money tree", insisting that the government could not afford to borrow to significantly increase spending. 

It was precisely this kind of economic fatalism that Cable took a razorblade to. He denounced as "absurd" the claim that capital spending could not be "greatly expanded" and attacked the "pessimists" who say "the central government is incapable of mobilising capital investment quickly". 

Borrowing for growth, he added (rather than imposing further cuts elsewhere), "would inject demand into the weakest sector of our economy – construction – and, at one remove, the manufacturing supply chain (cement, steel). It would target two significant bottlenecks to growth: infrastructure and housing."

What do Labour's lost voters make of the Labour leadership candidates?

What does Newsnight's focus group make of the Labour leadership candidates?

Tonight on Newsnight, an IpsosMori focus group of former Labour voters talks about the four Labour leadership candidates. What did they make of the four candidates?

On Andy Burnham:

“He’s the old guard, with Yvette Cooper”

“It’s the same message they were trying to portray right up to the election”​

“I thought that he acknowledged the fact that they didn’t say sorry during the time of the election, and how can you expect people to vote for you when you’re not actually acknowledging that you were part of the problem”​

“Strongish leader, and at least he’s acknowledging and saying let’s move on from here as opposed to wishy washy”

“I was surprised how long he’d been in politics if he was talking about Tony Blair years – he doesn’t look old enough”

On Jeremy Corbyn:

"“He’s the older guy with the grey hair who’s got all the policies straight out of the sixties and is a bit of a hippy as well is what he comes across as” 

“I agree with most of what he said, I must admit, but I don’t think as a country we can afford his principles”

“He was just going to be the opposite of Conservatives, but there might be policies on the Conservative side that, y’know, might be good policies”

“I’ve heard in the paper he’s the favourite to win the Labour leadership. Well, if that was him, then I won’t be voting for Labour, put it that way”

“I think he’s a very good politician but he’s unelectable as a Prime Minister”

On Yvette Cooper

“She sounds quite positive doesn’t she – for families and their everyday issues”

“Bedroom tax, working tax credits, mainly mum things as well”

“We had Margaret Thatcher obviously years ago, and then I’ve always thought about it being a man, I wanted a man, thinking they were stronger…  she was very strong and decisive as well”

“She was very clear – more so than the other guy [Burnham]”

“I think she’s trying to play down her economics background to sort of distance herself from her husband… I think she’s dumbing herself down”

On Liz Kendall

“None of it came from the heart”

“She just sounds like someone’s told her to say something, it’s not coming from the heart, she needs passion”

“Rather than saying what she’s going to do, she’s attacking”

“She reminded me of a headteacher when she was standing there, and she was quite boring. She just didn’t seem to have any sort of personality, and you can’t imagine her being a leader of a party”

“With Liz Kendall and Andy Burnham there’s a lot of rhetoric but there doesn’t seem to be a lot of direction behind what they’re saying. There seems to be a lot of words but no action.”

And, finally, a piece of advice for all four candidates, should they win the leadership election:

“Get down on your hands and knees and start praying”
