A powerful paedophile network may have operated in Britain protected by its connections to Parliament and Downing Street, a senior Labour politician suggested. Tom Watson, the deputy chairman of the Labour Party, called on the Metropolitan Police to reopen a closed criminal inquiry into paedophilia. Mr Watson referred to the case of Peter Righton, who was convicted in 1992 of importing and possessing illegal homosexual pornographic material. Righton, a former consultant to the National Children's Bureau and lecturer at the National Institute for Social Work in London, admitted two illegal importation charges and one charge of possessing obscene material. He was fined 900. Mr Watson said the evidence file used to convict Righton if it still exists, contains clear intelligence of a widespread paedophile ring". He told a hushed Commons: "One of its members boasts of a link 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." The Independent understands that Mr Watson's comments were [aimed] at a living person associated with Margaret Thatcher's administration. They are thought to involve the activities of the Paedophile Information Exchange, a pro-paedophile group in existence between 1974 and 1984, which believed there should be no age of consent.
