The Giving Victims a Voice report into allegations made against the disgraced DJ and presenter suggests Savile’s offending covered a period from 1955 to 2009.

The majority of Savile’s offences were committed between the ages of 40 and 50, with 73 per cent of his attacks perpetrated against children.

He abused children at 14 hospitals including Great Ormond Street, and a children’s hospice.

The report says that 34 of these attacks involved “rape or penetration” and that 450 victims have alleged incidents against Savile.

Commander Peter Spindler of the Metropolitan police said: “The report paints a stark picture emphasising the tragic consequences of when vulnerability and power collide. His offending footprint was vast, predatory and opportunistic.”

Keir Starmer, Director of Public Prosecutions, said: “I would like to take the opportunity to apologise for the shortcomings in the part played by the CPS in these cases.

“If this report and my apology are to serve their full purpose, then this must be seen as a watershed moment.”

Savile is believed to have committed an offence during the filming of the last ever Top of the Pop in 2006.

The youngest of his victims was an eight-year-old boy.
