Every time that George Osborne announces new restrictions on benefits it has as much to do with tripping up Labour as it does with saving money. Aware of how much support the party's perceived softness on claimants cost it in 2010, he aims to paint it as "the welfare party".
Having opposed most of the £18bn of cuts previously announced by the coalition, it is a trap Ed Miliband and Ed Balls are now keen to avoid. After Osborne announced in the Budget that he would unveil plans to cap Annually Managed Expenditure (AME) in the Spending Review, (the area of public spending that includes volatile and demand-led items such as welfare, debt interest and EU contributions), Labour pre-empted him by outlining its own cap on "structural" welfare spending and announced that it would remove Winter Fuel Payments from the wealthiest 5 per cent of pensioners, a (rather successful) attempt to redirect attention on to the main driver of higher social spending: an ageing population.
In today's review, Osborne announced a series of tougher rules for claimants, including a seven-day wait before they can claim benefits, a duty to learn English (with benefits docked if they fail to attend language classes), the introduction of weekly, rather than fortnightly, visits to the jobcentre for half of all jobseekers, a requirement for all single parents of children aged three or over to prepare for work and a duty for individuals to prepare a CV and register for an online job search before they can receive benefits.
In response, it was notable that Balls avoided opposing any of the measures outright. He told BBC News:
We need to look at the detail, obviously. On the welfare things, English language for incoming migrants - definitely. For the seven-day - is it going to be a blank cheque for Wonga? Let's look at the detail. If it saves money and it works, fine.
So, while expressing some scepticism, Balls has essentially accepted the principle of a seven-day wait for benefits provided that it "saves money" (it will, but at a terrible cost to claimants forced to turn to foodbanks) and that it "works" (again, based on Osborne's definition, it will). Nor, the party signalled, will it oppose the requirement for single parents to look for work.
In his statement, Osborne also served notice of the biggest welfare trap of all. He announced that his new cap on total benefit spending would be set in next year's Budget and would apply from April 2015. Expect him to adopt the toughest limit possible and then challenge Labour to match it. Should it do so, it will be accused of signing up to an unconscionable attack on the poorest. Should it not, it will be accused of failing to control runaway spending. Having signalled that it will not borrow more to reverse cuts to current spending (only to invest in capital projects such as housing), any difference will need to be funded through tax rises.
