Virginia Giuffre has shared new details of the night she allegedly had sex with Prince Andrew.

Secret communications between the late Jeffrey Epstein and prominent lawyer Alan Dershowitz — who helped secure the paedophile’s controversial 2008 plea deal — could be made public, it was revealed in court on Monday.

The disclosure came as lawyers for self-proclaimed “sex slave” Virginia Roberts Giuffre, who now lives in Australia, said they intended to seek the privileged communications to prove that Mr Dershowitz had personal motivations for orchestrating the sweetheart deal.

In Ms Giuffre’s defamation suit, which was filed against Mr Dershowitz in April in the Southern District of New York, she accuses him of knowingly making “false and malicious defamatory statements” against her. She claims to have been a victim of sex trafficking and abuse by Epstein when she was underage.

Ms Giuffre’s lawsuit alleges that “Dershowitz was Epstein’s lawyer, close friend, and co-conspirator. Dershowitz was also a participant in sex trafficking, including as one of the men to whom Epstein lent out Plaintiff for sex.”

Ms Giuffre has made similar claims about Mr Dershowitz in court filings in the past but he has repeatedly denied the allegations, dismissing her as a liar and an extortionist, and countersuing for defamation.

Ms Giuffre’s lawyer Charles Cooper said at a hearing in Manhattan Federal Court on Monday he would “seek discovery into Mr Dershowitz’s lawyer-client relationship with Mr Epstein”.

Epstein died in August while awaiting trial on sex trafficking charges; the New York City medical examiner determined he had died by suicide.

“If Mr Dershowitz was involved with Mr Epstein in the activities alleged, his communications with Mr Epstein, and the motivations Mr Dershowitz had to negotiate the plea deal that has become so controversial will be relevant and important,” Mr Cooper said.

“Mr Dershowitz’s denial is quite sweeping.”

In his denial, Mr Dershowitz claimed he never had sex with anyone other than his wife.

Mr Cooper noted that a recent New York Times article made reference to “what purports to be a recording” of Mr Dershowitz having sex with a woman in Epstein’s apartment.

Manhattan federal court judge Loretta Presks, who is overseeing the defamation case, heard both parties are seeking to view the video – which Mr Dershowitz claims is a fake.

Mr Cooper said his legal team wasn’t investigating whether Mr Dershowitz “never had sex, generally, with anyone other than his wife”.

He said the question was whether Mr Dershowitz “has had sex with anyone in connection with Mr Epstein’s operation”.

Another accuser previously stepped forward after Ms Giuffre filed her suit saying in an affidavit: “I witnessed Dershowitz at the NY mansion going upstairs at the same time there were young girls under the age of 18 who were present upstairs in the house,” the document reads.

Meanwhile, Ms Giuffre’s lawyers also revealed they plan to file an amended lawsuit against Mr Dershowitz citing claims under the Child Victims Act. The recently enacted law opens a window allowing victims of childhood sexual abuse to file lawsuits against their abusers, even if the statute of limitations has passed.

The amended complaint will also include new libel allegations against Mr Dershowitz for statements made about Ms Giuffre in his new book, Guilt by Accusation and an allegation that Mr Dershowitz violated the federal electronic communications Wiretap Act when he secretly recorded a conversation with David Boies, who has previously represented Ms Giuffre.

Mr Dershowitz claims in the tapes, which are currently under forensic examination, Mr Boies admits that Ms Giuffre is lying about her interactions with Mr Dershowitz.

Mr Dershowitz’s lawyer Howard Cooper said they would be moving to dismiss the amended complaint.

“I think there’s irrefutable evidence she wasn’t a child and doesn’t qualify,” Howard Cooper said of Ms Giuffre’s plan to file under the CVA.

Monday’s hearing also turned to discussions of a New York Times report detailing allegations that Mr Boies planned to use footage — allegedly from Epstein’s house and containing images of powerful men having sex with underaged girls — to try and coerce settlements.

Mr Dershowitz’s lawyer said Ms Giuffre was suing his client for essentially calling her a liar.

“I’m well aware of that counsel,” the judge responded.

Ms Giuffre’s lawyer said that description was an understatement and alleged there had been “an extraordinary effort” by Ms Giuffre and her legal team to blackmail and extort his client.

Outside court, Mr Dershowitz told reporters he would happily release his communications with Epstein, saying he has “nothing to hide”.

“It’s up to Epstein’s lawyers,” he said.

Mr Dershpwitz said he had never even met Ms Giuffre.

“She told the FBI she never met me, she told all of her best friends and her boyfriend she never met me,” he said. “Suddenly, she remembered having met me seven times only after she meets her lawyers as part of this shakedown plot.”

Mr Dershowitz also claimed Ms Giuffre wasn’t underage when she was trafficked and accused her of changing her story to fit the law.

“This is a woman has a long history of falsely accusing prominent men for money, and she has falsely accused me for money,” he said.

“And that will be proved beyond any doubt at the trial.”
