Around 600 people have come forward since the establishment of Operation Yewtree, raising 450 cases relating to Savile.

Within the 214 recorded crimes, there were 126 indecent acts and 34 cases of rape or penetration were recorded.
The report found that while most of the attacks were "opportunistic", there were also some cases of grooming or planned assaults.
The earliest reported incident was in 1955 in Manchester and the final reported offence was in 2009.
NSPCC director of child protection advice and awareness Peter Watt said: "The sheer scale of Savile's abuse over six decades simply beggars belief.
"He is without doubt one of the most prolific sex offenders we have ever come across and every number represents a victim that will never get justice now he is dead.
"But with this report we can at least show his victims that they have been taken seriously and their suffering has been recognised."
He added: "We also know from the huge increase in calls to the NSPCC helpline about sexual abuse that the problem did not die with Savile.
"Since the Savile scandal broke we have seen a surge in contacts about child abuse, both past and present, with many victims speaking out for the first time."
Watt continued: "Almost 800 additional children have been protected from abuse because the publicity around this case prompted people to contact our helpline.
"We are optimistic that this signals a watershed moment for child protection in this country. We must seize the opportunity if we are to make a lasting change."
Today's 30-page report, titled Giving Victims a Voice, covers abuse over 28 police force areas, including that at the BBC, Stoke Mandeville Hospital, Leeds General Infirmary, Broadmoor high-security psychiatric prison and Wheatfields Hospice in Leeds.
The entertainer, who died in October 2011 at the age of 84, was also linked to abuse at Duncroft Approved School in Surrey and Jersey children's home Haut de la Garenne.
ITV's October 2012 broadcast Exposure: The Other Side to Jimmy Savile prompted other victims to speak out, and later caused a media storm as it emerged a Newsnight investigation into Savile scheduled for a year earlier had been dropped by the BBC.
The fallout and later botched Newsnight programme which wrongly accused Lord McAlpine of abuse led to the resignation of BBC director general George Entwistle and others.
The Pollard report said that the decision to axe the original show was "flawed" but taken in good faith.
A second report by Ken MacQuarrie into the McAlpine broadcast damned a "serious failure of BBC journalism".
