The changes in eligibility for personal independence payments and the cuts to universal credit incapacity payments are projected by the OBR to save the government £4.8bn a year by 2029-30.

A spokesperson for Biden, 82, said "evidence of aging is not evidence of mental incapacity" and maintained the Democrat had been "a very effective president".

Those changes would include stricter tests for personal independence payments and the halving of incapacity benefits under universal credit for new claimants.

The government's changes include stricter eligibility tests for those claiming personal independence payments and a freezing of incapacity benefits under universal credit.
