Martin Lewis has urged women to check if they are due thousands of pounds on their state pension.
The Money Saving Expert said more than 230,000 women could be due a payout – with the average amount being more than £6,000. Women who hit the state pension age before April 2016 - mainly married women (including widows and divorcees), and over-80s (whether married or not) - may have been underpaid.
The error is on behalf of the Department for Work and Pensions' computer systems and though the repayments are automatic, not all women will receive them.
