Max Clifford has been "unmasked as a ruthless and manipulative sex offender who preyed for decades on children and young women", the director of children's charity the NSPCC has said.
Responding to the eight-year sentence handed down to the shamed celebrity publicist at Southwark Crown Court, Mr Watt said:
Clifford was a rich and influential man who dined with the stars but the way he manipulated and groomed his victims is typical of many sex offenders. He exploited their vulnerabilities, using lies and coercion to get what he wanted.
Throughout the court case Clifford has behaved dismissively and arrogantly towards his victims and the suffering he has caused them. He made them go through a long and painful court case and relive their traumatic experiences by not pleading guilty.
