Frank Field MP 'gobsmacked' by ESA pay-out errors

Frank Field, chair of the work and pensions select committee, said miscalculations affecting Employment Support Allowance payments were of "historic proportions".

The BBC understands that assessors wrongly calculated the income of around 75,000 claimants - and may have underpaid them.

Mr Field told BBC News that people had been "wrongly impoverished" as a result of the errors.
