Virginia Roberts Giuffre, one of Jeffrey Epstein's alleged "sex slaves", has accused the Duke of York of sexually abusing her when she was underage. The embattled British royal, however, has vehemently denied any wrongdoing.

Prince Andrew's attorneys have asked the judge to keep evidence secret as his legal battle with Virginia Roberts Giuffre over alleged sexual assault is ongoing, The Times reported.

According to the report, the duke's lawyer Andrew Brettler requested that US District Judge Lewis Kaplan keep Andrew's response to some of Giuffre's claims "sealed".

These claims have not been disclosed either, with Prince Andrew only being accused of forcibly having sex with then-17-year-old Giuffre at the London estate of late American sex offender Jeffrey Epstein.

The secrecy around the case is notable, as reports emerged earlier in the week suggesting that even Queen Elizabeth II (who happens to be paying Andrew's hefty legal fees in the case) is being left "in the dark" about her son's defense strategy. Prince Charles and Prince William are also reportedly unaware of the details of Andrew's legal response, as the duke has reportedly had "little or no discussion" about it with senior British royals.
