Judges, peers and MPs are among 20 prominent public figures who abused children for decades, a former child protection manager has said.
Peter McKelvie, who worked on the conviction of paedophile Peter Righton, said there was a “powerful elite” of paedophiles who carried out “the worst form” of abuse.
There is evidence linking the former politicians to an alleged paedophile network, he said.
Lord Warner, the former health minister, said the allegations were credible.
Mr McKelvie triggered a police investigation in 2012 when he revealed there were seven boxes of potential evidence of a powerful paedophile network, including letters between Righton and other paedophiles, being stored by West Mercia Police.
