Labour takes the third U-turn this month.
The government has confirmed it will make changes to its welfare bill following pressure from Labour rebels on its planned changes to benefits.
In a letter to MPs, Work and Pensions Secretary Liz Kendall said claimants of the Personal Independence Payment (Pip) will continue to receive what they currently get, as will recipients of the health element of Universal Credit. Instead, planned cuts will only hit future claimants.
The concessions amount to a massive climbdown from the government, which was facing the prospect of defeat if it failed to accommodate the demands of over 100 backbenchers.
A No 10 spokesperson said in a statement: “We have listened to MPs who support the principle of reform but are worried about the pace of change for those already supported by the system.
“This package will preserve the social security system for those who need it by putting it on a sustainable footing, provide dignity for those unable to work, supports those who can and reduce anxiety for those currently in the system.
“Our reforms are underpinned by Labour values and our determination to deliver the change the country voted for last year.”
Ministers are also expected to fast-track a £1bn support plan originally scheduled for 2029.
