The Government is working โ€œflat outโ€ to cut the ballooning costs of welfare spending, Prime Minister Andy Burnham has insisted after the Chancellor faced scrutiny about the rising costs of benefits in wake of the Budget.

John Healey was repeatedly pressed about the cost of welfare by broadcasters, after the Office for Budget Responsibility (OBR) warned sickness and disability benefits could cost ยฃ100 billion a year before the end of the decade.

But Treasury officials pushed back against media interpretations of Mr Healeyโ€™s responses which suggested he wanted the bill to start falling before the next election.

The Prime Minister was asked about his timeframe for reducing the benefit bill during a visit to Derby on Thursday.

He told reporters: โ€œWe want to get the welfare bill down as quickly as possible, and weโ€™re working flat out to that end.

โ€œNow that we are through the Budget, the big next priority in front of us is the publication of the Milburn report, long awaited, but itโ€™s coming soon.

โ€œWe just want to get stuck into supporting people to help people off benefits and into work.

โ€œThereโ€™s no delay there.

โ€œWe want that to happen as quickly as possible.โ€

In an interview with the BBCโ€™s Today programme, Mr Healey was asked whether the benefits bill would be cut before the next general election.

He told the BBC: โ€œThere will be a reduction in the benefits bill, weโ€™ll do that in a Labour way and weโ€™ll do that because it is simply not good for Britain or progressive to have a bigger and bigger benefits bill.โ€

However, Treasury officials later stressed he was not setting a timeframe for the welfare reduction.

The Chancellor also said on LBC Radio that welfare reform would not amount to โ€œcrude benefit cutsโ€ which would be a โ€œpressure too farโ€ when people were โ€œsufferingโ€ with the cost of living.

Downing Street insisted the Chancellor had remained โ€œcompletely in line with what the PM has said over the last few months that the welfare bill needs to come downโ€ and added the Government was not โ€œsetting an arbitrary target or timetable on thatโ€.

More details about the Governmentโ€™s plans to bring down benefits spending will follow the publication of two major reviews next month, the Prime Ministerโ€™s official spokesman said.

โ€œWeโ€™ll bring the bill down by tackling the underlying drivers of spending, getting more people into work, and matching support with clear opportunities and responsibilities to engage with the Governmentโ€™s support offer,โ€ the spokesman added.
