Thousands of savers paid £600 by mistake but can KEEP the cash - see who is affected

Premium Bond provider National Savings and Investments (NS&I) accidentally paid out around £600 to more than 3,000 savers last year.

The mistake cost the Government-backed bank around £2million, according to its annual accounts.

Some savers could have received more, or some could have received less, as the £600 figure is just the average amount.
