One of Tony Blair’s ministers was among a group of men suspected of sexually abusing children at a home run by a convicted paedophile.
But the probe was halted soon after an ex-social services boss told police of his alleged evening visits in the early 1980s.
Official documents seen by the Daily Mirror during a 16-month investigation reveal former residents told detectives that a group of paedophiles attacked children in a private flat in the home.
But two former Lambeth social services employees involved in the case suspect a cover-up because experienced detective Clive Driscoll was removed from the investigation and given other duties.
One, a former manager who alerted police in 1998, said: “One wonders why Scotland Yard would be so desperate to stop it being investigated.
“I believe it was stopped because somebody in power was trying to prevent any further investigation into the politician.”
