Max Clifford is an unrepentant sadist who, driven by sex and money, "delighted in humiliating his victims", former Tory minister David Mellor has told ITV News.
Mellor was forced to resign in 1992 after Clifford took details of the politician's affair with actress Antonia de Sancha to the tabloids, including spicing up the story with lies.
Responding to Clifford's jailing, Mellor said the celebrity publicist "thought he was above retribution" and admitted that he took a "little bit of pleasure" at seeing him convicted.
"He came out this morning and waved two fingers at the judge ... and the judge waved two even bigger fingers back," Mellor added.
The custody image of Max Clifford has been released by the Metropolitan Police following his sentencing to eight years in prison for a string of indecent assaults.
Max Clifford's solicitor has said the disgraced celebrity publicist is "seriously" considering an appeal against his eight-year sentence as well as an appeal against his conviction.
The comment from Clifford's legal camp came as one legal expect expressed his surprise at the length of the sentence handed down and suggested it was "significantly" likely that an appeal could succeed.
Simon McKay, a criminal human rights lawyer at McKay Law, said he was "very surprised" at the length of the sentence, because it "creates the opportunity for the sentence to be appealed", adding: "And I don't think that's good for the victims."
Judge Anthony Leonard condemned Max Clifford for causing more trauma for his victims with his "contemptuous" behaviour during his trial, including attempts to "trivialise" accusations against him by mimicking a reporter outside court.
The judge referred directly to Clifford's appearance behind Sky News reporter Tom Parmenter as he recorded a summary of the latest evidence during the trial at Southwark Crown Court.
"I find your behaviour to be quite extraordinary and a further indication that you show no remorse," the judge said before sentencing Clifford to eight years for the historic indecent assaults.
"(The) additional element of trauma caused by your contemptuous attitude is something that I shall take into account in sentence," he added.
"I can only hope that these proceedings will provide all your victims with some sort of closure."
The eight-year jail term handed to Max Clifford reflects the impact his crimes have had on his young women victims, a spokesperson for charity Victim Support has said.
Adam Pemberton, the charity's assistant chief executive, said it was the "compelling testimony" of the abused women - described as "liars" and "fantasists" by Clifford in court - that convicted him.
He paid tribute to the women for "finding the strength" to give evidence against the powerful PR man.
The Director of Public Prosecutions has welcomed the conviction and sentencing of Max Clifford for historic indecent assaults, saying he has "rightly been held to account", and praised his victims for reporting the abuses.
“The prosecution was built with evidence demonstrating a pattern of behaviour where unconnected victims told of strikingly similar experiences over a number of years," Alison Saunders said.
"I would like to thank all the victims for coming forward and giving evidence in difficult circumstances."
She urged other victims to report their claims of abuse, "no matter who is alleged to have carried out the abuse or when".
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.
Celebrity publicist Max Clifford has been described as living a "double existence" during his decades influencing the media after being sentenced to eight years for a string of indecent assaults.
Passing sentence at Southwark Crown Court, Judge Anthony Leonard told him:
Although your charitable work has gone on for a long time after your offending stopped, I cannot ignore that for decades you were leading a double existence.
Judge Leonard said he believed Clifford's personality and profile were why the crimes he committed had not been made public sooner.
Some of Clifford's supporters, sitting behind the dock in the public gallery, broke down in tears as he was sentenced. The 71-year-old was taken away to the cells.
Max Clifford has been told his historic indecent assaults on young women would have resulted in an even more severe punishment had the offences been committed in recent years.
Judge Anthony Leonard said Clifford was charged under an act from 1956, which set the maximum term for such assaults at two years, because his offences took place between 1977 and 1984.
The judge said under later legislation passed in 2003, the maximum term would have been 10 years.
The worst instances would have been charged as rape or assault by penetration, which attract a maximum life term, Southwark Crown Court heard.
Max Clifford has been told he must serve at least half the eight-year sentence handed down at Southwark Crown Court in prison.
Judge Anthony Leonard told Clifford he had shown a "contemptuous attitude" and "quite extraordinary behaviour" while showing "no remorse" for his crimes.
The judge said: "These offences may have taken place a long time ago, when inappropriate and trivial sexual behaviour was more likely to be tolerated, but your offending was not trivial, but of a very serious nature."
