Two lawyers representing Virginia Roberts, the woman at the centre of "sex slave" allegations involving Prince Andrew, are suing Harvard Law Professor Alan Dershowitz, who is also accused of having sex with her when she was underage.
Dershowitz was named alongside the Duke of York in US court documents in a case involving disgraced financier Jeffery Epstein and Virginia Roberts – known as Jane Doe #3 .
Roberts claims she was forced to have sex with Dershowitz, Prince Andrew and several other people by Epstein when she was 17 and therefore under the age of consent in the US state of Florida at the time of the alleged offences.
Dershowitz previously began legal proceedings to clear his name in what he described as "totally false and outrageous" allegations and gave several public interviews to deny he ever had sex with Roberts. He also vowed to seek the disbarment of the two layers representing Roberts - Paul Casell and Bradley Edwards - and also claimed the lawyers knew the charges were false when they filed them.
Casell and Edwards have now filed a counter defamation lawsuit against Dershowitz after they accused him of launching a public media assault on Roberts' reputation and character, according to court documents.
The pair accuse Dershowitz of making several defamatory statements in "reckless disregard", in order to maintain his innocence. Cassell and Edwards also claim Dershowitz defamed them by accusing the pair of "deliberate misconduct and unethical behaviour warranting disbarment" during his media interviews.
In response, Dershowitz said he is "thrilled" to be sued by the lawyers.
"This gives me an opportunity to depose them and prove beyond any doubt that they concocted the entire story out of whole cloth and that they did not do a proper investigation and that they have falsely accused me," Dershowitz added.
Buckingham Palace have also repeatedly denied the allegations against Prince Andrew.
