A prime minister's dementia advisor, Johnny Timpson, resigned in protest over the government's policy of reclaiming benefits overpayments.
He was particularly concerned about the impact on families of elderly people with dementia, citing an example of a 92-year-old who was asked to repay £7,000.
The Department for Work and Pensions (DWP) defended its commitment to fairness in the welfare system.
Timpson spoke to the BBC before a work and pensions committee hearing with the disabilities minister and the DWP's fraud, error and debt strategy director.
The text discusses the issue of clawbacks, or the repayment of overpaid benefits, and the challenges faced by unpaid carers in dealing with this complex system.
Mr. Timpson, a minister, expressed concern that the intricacy of the benefits system often leaves carers, who are already dealing with the demands of caring for a loved one with dementia, unable to understand and repay their debts.
Overpayments can go on for years, and with carers often having given up work, they may no longer have the financial means to repay these debts.
Mr. Timpson, a business leader, emphasized the importance of organizations identifying vulnerable customers and intervening to prevent harm.
He criticized the UK government, represented by the Department for Work and Pensions (DWP), for not doing enough in this regard.
Mr. Timpson suggested that the DWP has the power to help vulnerable customers and urged them to use data to identify potential harm and intervene promptly to prevent crises.
