THE Tories won’t tell voters who will be the latest to fall victim to their next assault on welfare spending, Work and Pensions Secretary Iain Duncan Smith admitted yesterday.

Documents leaked from his department show cuts to disability benefit and compensation for injured workers are among policies being considered in order to cut £12 billion from the welfare budget.

But Mr Duncan Smith revealed the Tories may not think it “relevant” to explain where the cuts will be made before the general election.

“We may, we may not, decide that it’s relevant to put something out there about some of those changes,” he told the BBC’s Andrew Marr show.

“As and when the time is right, we will make it very clear what our position is.”

Institute for Fiscal Studies director Paul Johnson said the £12bn cut would see welfare spending slashed by 10 per cent in just three years.

Speaking on the same show, he warned: “That would require pretty dramatic changes to things like housing benefit and disability benefits.”

Shadow work and pensions secretary Rachel Reeves challenged the Tories to “come clean” with the public about the impact of their plans.

“Iain Duncan Smith’s refusal to admit how children, disabled people, carers and working families will be hit by secret Tory plans six weeks before the election is completely unacceptable,” she said.

Ms Reeves, who sparked controversy recently by saying Labour is “not the party of people on benefits,” said Labour would reduce social security spending by tackling low pay and housing costs.

Mr Johnson said Labour’s plans for cuts were unclear but believed to be “quite a lot less” severe than the Tories.
