Ed Miliband tore apart yesterday's "more of the same" Budget from a "downgraded Chancellor."
The Labour leader used forecast growth figures for 2013, which was slashed from 1.2 to just 0.6 per cent, to bash George Osborne over the head with.
Mr Miliband said growth was down last year, this year and next year and that Office for Budget Responsibility stats confirmed that British people will be worse off in 2015 than in 2010.
"It's official - you are worse off under the Tories," he said.
Mr Miliband said that families will have to wait two years for Mr Osborne's proposed 20 per cent tax relief on childcare, but "for the richest in society, they just have to wait two weeks for the millionaires' tax cut to kick in."
He challenged members of the Cabinet to put their hand up if they did not benefit from the 50p top-rate tax cut. None did.
Mr Miliband ridiculed the Chancellor's tired mantra by saying that the only time the British public felt "all in it together" was when they booed Mr Osborne as he handed out Paralympic medals at the Olympic stadium last year.
He also exposed the hypocrisy of the Chancellor and Prime Minister David Cameron for suggesting that the country would borrow more under Labour when borrowing soared to £114 billion this year, up from £108bn.
Meanwhile shadow chancellor Ed Balls, who will deliver his response to the budget today, could be heard shouting to Mr Osborne: "Stop sneering."
