The Department for Work and Pensions (DWP) mistakenly sent more than half a billion pounds to deceased pensioners over the last five years, official figures have revealed, with most of this left unrecovered.
Since 2019, £512m has been overpaid in state pension and pension credit, of which only £255m has been sent back. The largest sum of overpayments was made just last year, when £159.2m was transferred.
