Investigation found some women on state pensions were underpaid over last 20 years
About 200,000 women could be in line for pension back-payments averaging £13,500 following an investigation into the underpayment of state pensions over the last 20 years.
As Guardian Money reported last month, some of the affected women received pensions of as little as 86p a week, when they were in fact entitled to 60% of the basic state pension – about £80 a week.
