Since Labour MP Tom Watson stood up in the Commons in October 2012 to ask Prime Minister David Cameron to probe a high-powered paedophile ring with links to Number 10, the Sunday People has led the way.
We have produced a string of exclusive stories tracking the progress of Operation Fairbank and its offshoots.
Shocking revelations about the Elm Guest House dominated the early part of our investigation as traumatised victims came forward.
They claim the property in Barnes, south-west London, was used by a host of Establishment figures who attended sex-abuse parties there.
Among the names said to have visited the infamous site were Leon Brittan, Cyril Smith, Anthony Blunt, Nicholas Fairbairn and Sir Peter Morrison.
Elm Guest House was run by Carole Kasir , who later died of an apparent insulin overdose.
It was the subject of Met Police operations but none of its VIP visitors were arrested. And it was only after Operation Fairbank got going that victims’ claims were seriously investigated.
