It is three days since Professor Alexis Jay published her report into child abuse in Rotherham, and still the sickening implications are sinking in at Westminster. David Cameron had no inkling that it was coming, which is why he has said so little about it. The report, commissioned by the borough council, was expected to mop up any points left over from a notorious paedophile case four years ago. Instead, Prof Jay discovered a far greater, longer-running scandal with more than 1,400 victims. Suddenly, ministers have been presented with one of the most horrific catalogues of abuse in recent British history.
