His hostile reaction suggested that it might prove difficult for the Conservatives and Lib Dems to reach agreement on a second coalition if the 2015 election results in another hung Parliament. Both Labour and the Lib Dems called yesterday for the deficit to be cut in a "fair way".
Osborne has set his face against any tax rises to balance the books, while the Lib Dems and Labour both support a mansion tax on homes worth more than 2 million. Clegg made clear he would support further tax increases on the rich, to fill 20 or 25 per cent of the gap, with the rest found through cuts.
The Chancellor's tough message, in a speech in Birmingham and media interviews, was designed to put Labour on the spot in the run-up to the election.
If Labour refuses to back big welfare cuts, the Tories will argue that it lacks economic credibility and would raise taxes. Osborne believes further welfare savings will prove popular with many swing voters.
Osborne said government, and the welfare system, were "going to have to be permanently smaller". But he appeared to rule out cuts to the health budget or pensioners' benefits such as winter fuel allowances, free bus passes and TV licences.
Paul Johnson, director of the Institute for Fiscal Studies, said: "Wherever you look, you are taking money either from people who are poor, from people who are sick and disabled or people with children, none of which looks terribly easy to achieve, but these are difficult times."
Ed Balls, the shadow Chancellor, said: "Labour will have to make cuts and in 2015-16 there will be no more borrowing for day-to-day spending ... But we will get the deficit down in a fair way, not give tax cuts to millionaires. And we know that the way to mitigate the scale of the cuts needed is to earn and grow our way to higher living standards for all."
A Conservative spokesman replied: "Ed Balls has confirmed that Labour's choice is for more of the same - more borrowing, more spending on welfare and more taxes."
