A man living with kidney failure said the system for personal independence payments (Pip) was not fit for purpose after he was rejected for the benefit twice.
Tony Henderson, 55, from Bacton, Norfolk, has dialysis for about four hours a day, six days a week, and has had three heart attacks in 12 months due to strain being put on his heart from blood being pumped around his body.
Despite the government reversing plans to tighten eligibility criteria for Pip in July, Mr Henderson said that the "tick-box system" was still not "targeting the right people".
The Department of Work and Pensions said an ongoing review would ensure Pip was "fit and fair for the future".
