Deputy Prime Minister Nick Clegg has defended plans for a three-year benefits squeeze as he faced party dissent among his own MPs ahead of a key Commons vote.
In Commons clashes ahead of the debate - deputy Labour leader Harriet Harman said the Government had "failed on compassion".
But Mr Clegg questioned why the Opposition supported a 1% pay rise cap for public sector workers but not the curb on benefit payments and where it would find the savings.
MPs have voted in favour of a Government measure to cap benefits rises. The Work Secretary says it will save £5bn from the welfare bill.
The Department for Work and Pensions has calculated the savings that the exchequer could expect if the benefit cap passes this evening.
