Robert Joyce, Senior Research Economist at the Institute for Fiscal Studies (IFS) has told ITV News that the 1% benefits cut will affect both those who work and those who do not.
He added that although there will be a greater proportion of people who do not work affected by the cap, the fact that the cuts will hit both those in and those out of work will mean that, "the impact on people's incentive to move in to work will be somewhat mixed."
And that for some people the cuts will mean they are better off out of work.
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.
