The information is not available in the format requested. For details of the amount of overpayment in bereavement benefit and widow’s benefits combined, due to official error, I refer the hon. Member to the written answer I gave the hon. Member for Yeovil (Mr. Laws) on 18 April 2007, Official Report, columns 697-700W.
There are no reliable estimates of the amount of underpayment in these benefits.
