Labour MP Tom Watson argued in parliament last week that a key a senior aide to a former prime minister had abused children.
Watson said evidence used to convict sex offender Peter Righton more than 20 years ago contained far wider implications.
He told MPs, “The evidence file used to convict Righton, if it still exists, contains clear intelligence of a widespread paedophile ring.
“One of its members boasts of his links to a senior aide of a former prime minister, who says he could smuggle indecent images of children from abroad.
“The leads were not followed up, but if the files still exist, I want to ensure that the Metropolitan Police secure the evidence, re-examine it, and investigate clear intelligence suggesting a powerful paedophile network linked to Parliament and No 10.”
Meanwhile recriminations and allegations continue to swirl at the BBC about who knew what about Jimmy Savile. Sir Roger Jones, a former BBC governor, said he kept Savile away from the corporation’s charity Children in Need.
