I thank my hon. Friend for her service on the Treasury Committee; she is doing a sterling job as its Chair. This is a really important issue. Last year HMRC undertook a pilot to try to find a way to reduce fraud in the child benefit system. That measure is expected to save £350 million over the next five years, and we have already managed to prevent £17 million in wrongful payments, but my hon. Friend is right to say that a very small number of claimants had their child benefit incorrectly removed. I am really sorry that that happened. HMRC is writing to those who have been affected and ensuring that people who should get their child benefit payments do receive them.
