Deputy Prime Minister Nick Clegg said Conservatives were making a "monumental mistake" by imposing "cuts for cuts' sake" and trying to place all the burden of deficit reduction on the working-age poor.
"On the right, you've got a Conservative Party now who are driven, it seems to me, by two very clear ideological impulses," Mr Clegg told a Westminster press conference today.
"One is to remorselessly pare back the state, for ideological reasons just cut back the state.
"Secondly, and I think they are making a monumental mistake in doing so, they have said that the only section of society which will bear the burden of further fiscal consolidation are the working-age poor - those dependent on welfare."
