'We'd borrow more, but we'd use it better.' That was the message Ed Miliband found himself trying to get across when attacking David Cameron at PMQs today. He accused the Prime Minister of 'borrowing for failure', saying: 'He is borrowing for failure: that is the reality, and he is borrowing more for failure. That is the reality of his record. And here is the truth: they said they'd balance the books, they said they'd get growth, they haven't.' So Labour would borrow for success. What would that mean? Miliband decided to tease us by not mentioning how he'd do better borrowing. The two leaders traded quotes from various IMF staff members, as it's easy to find something in anything the IMF issues to suit your own theories about the economy.

Something quite curious is going to happen in the Commons this afternoon. David Cameron is encouraging his party to bang on about Europe. He has called a general debate, with the motion 'that this House has considered the matter of Europe', and it promises to be rather strange. The strangest thing is that a month ago, David Cameron would never have dreamed of tabling this sort of debate: his camp were busy in October trying to quell an uprising of backbenchers over the EU Budget. But after the speech that delighted even Mrs Bone last week, Cameron finally doesn't have to wait for a backbencher to pounce on him with entreaties on referenda and renegotiations: he's got nothing to hide now.

The Prime Minister is visiting Algeria today to pay his respects to the victims of the hostage crisis. He will also hold talks with Algerian Prime Minister Abdelmalek Sellal, and The Sun reports that he will ask Sellal's permission for MI6 to hunt down the attack's mastermind, Mokhtar Belmokhtar. This will mark the next move in the 'generational struggle' he described in his Commons statement. One of the first big steps in this struggle took place yesterday, with Downing Street confirming the deployment of more than 330 troops to North Africa to help the French action in Mali. None of those troops will be in combat roles, with the majority training forces in neighbouring countries.

So the Lib Dems got their way in the end, teaming up with Labour and minor parties to delay the changes to constituency boundaries until 2018 by 334 votes to 292. There were Tory rebels, too, and here, thanks to the Press Association, are their names: John Baron Philip Davies David Davis Sir Richard Shepherd The minor parties also voted with the Lib Dems and Labour: only the Alliance's Naomi Long voted with the Tories. Nadine Dorries, who remains suspended from the party, also supported the Conservatives. Tempers ran high in the debate itself, with Tory Penny Mordaunt MP accusing the Libs of casting 'flirtatious glances' across the Chamber at Labour and of exchanging their sandals for flip flops. She didn't mention whether they'd also ditched their socks with the sandals.

Aside from Ed Balls' attack on George Osborne for going 'on the piste' in Davos, Treasury question time in the Commons today was interesting not for what Labour did or didn't have to say, but for some of the pushes from the Tory backbench on helping those on low incomes. Sometimes it's the pattern of the questions that matters more than the individual answers. Many of the questions were pitches for the Budget, which also gave ministers the opportunity to not really answer them. Robert Halfon asked about reintroducing the 10p income tax rate, to which Greg Clark said he noted the MP's bid for the Budget, adding: 'But he will know that we have taken people out of tax, which has been important in restoring incentives and the rewards people have for going back to work.

Controversial though her proposals to relax quotas for childminders and nursery staff may be, no-one disagrees with Liz Truss' central mission to reduce the cost of childcare. The opposition know affordable childcare will form an important part of their 2015 offer, and have also been visiting countries such as Denmark to pick up some tips. It's also worth noting that Truss is only relaxing quotas in so far as childcare providers can take on one or two more children per staff member: a nursery worker will be allowed to look after four babies instead of three, and six under-fives rather than four. Similarly, a childminder will be able to look after two babies rather than one, and four under-fives, rather than three.

After publishing a paper highly critical of the Justice and Security Bill this morning, Andrew Tyrie is now considering making amendments to the legislation, I understand. MPs in a Bill committee will scrutinise the legislation line by line this week, and are expected to report to the House of Commons by mid-February. Tyrie, who also chairs the influential Treasury Select Committee, is considering tabling amendments to the Bill to be debated at that report stage. The Centre for Policy Studies paper which Tyrie has co-authored with Anthony Peto QC says that 'part 2 of the Bill should, preferably, be withdrawn, at least until the government can come back with more balanced proposals, accompanied by a more rigorous explanation of the need for them'.

The Tories in opposition were very keen on their 'Green Deal' for making existing housing stock energy efficient. It formed the cornerstone of their pledge when the Coalition formed to be the 'greenest government ever'. It had its big full launch today, with new loans available for homeowners to insulate their properties and pay back the money through their energy bills. The only problem is that the Green Deal isn't quite the big all-singing all-dancing deal the government envisaged. The idea was that big businesses would lead the way in providing the scheme, but one of the leading retailers who expressed initial interest in the scheme, Marks and Spencer, isn't involved.

George Osborne, Patrick McLoughlin and Simon Burns have been flying the flag for the second phase of High Speed Rail 2 this morning. Politically, Osborne and Co see rewards in a project aimed at closing the North/South divide, rewards clearly so great that the Chancellor doesn't mind the second half of the route zipping through his own constituency and irritating local councillors and campaigners. Osborne was careful to underline this when he appeared on breakfast television this morning, saying: 'Our country has become so unbalanced and for the last 15 years as a country we gambled on the City of London and its prosperity and look where that got us.

Nick Clegg was apparently just being self-critical in his House magazine interview when he said the Coalition hadn't got it right from the beginning on infrastructure. Those close to the Deputy Prime Minister are insisting that though speaking out on economic policy remains unusual in the Coalition, he was simply pointing out what has actually happened, with the government now offering more on capital spending. But at this morning's lobby briefing, the Prime Minister's official spokesman didn't exactly take that same tone. 'The Prime Minister's view is that it was the right decision to have made,' he said, pointing to increases in infrastructure spending in the last two autumn statements. 'More already is being done,' the spokesman added.

The government's gay marriage bill is published later today, after receiving its first reading in the Commons yesterday. How it's received by the Tory party will be an interesting indication of just how powerful David Cameron's EU speech was this week. When Maria Miller unveiled the 'quadruple lock' to protect the Church of England from being forced to conduct same sex ceremonies, she did so into a febrile Commons. In the tearooms, MPs quarrelled or shook their head at the exodus of stalwart Conservatives from their constituency parties. But the Prime Minister's speech gave the party such a shot in the arm on Wednesday that the atmosphere is currently very different.
