PMQs: Tom Watson on paedophile ring links to previous PM's aide

24 October 2012 Last updated at 13:12 BST

A Labour MP asked the prime minister about claims of a "powerful paedophile network linked to Parliament and No 10".

Tom Watson called for the Metropolitan Police to look at evidence around a "widespread paedophile ring" and allegations about child sex images and the senior aide of a former prime minister.

David Cameron said he was not sure which previous prime minister was being referred to, but he would check Hansard "to see what the government can do to give him the assurances he seeks".
