Prince Andrew, the Duke of York, has failed in his bid to get a civil case that alleges he sexually assaulted Virginia Giuffre dismissed by a US judge.
Ms Giuffre is suing the prince claiming he abused her when she was 17. Prince Andrew has consistently denied the allegations.
His lawyers said the case should be thrown out, citing a 2009 deal she signed with convicted sex offender Jeffrey Epstein. But a New York judge ruled that the claim could be heard.
The motion to dismiss the lawsuit was outlined in a 46-page decision by Judge Lewis A Kaplan of the United States District Court for the Southern District of New York.
In court documents, Ms Giuffre said she was the victim of sex trafficking and abuse by late billionaire financier Epstein.
Part of her abuse involved being lent out to other powerful men, she alleges.
Prince Andrew said in an interview with BBC Newsnight in 2019 that he had no recollection of ever meeting Virginia Giuffre.
His lawyers had argued that Ms Giuffre agreed in court in 2009 not to sue anyone else connected to Epstein when she settled her damages claim against the billionaire sex offender.
Prince Andrew, the third child and second son of Queen Elizabeth II and Prince Philip, Duke of Edinburgh, is ninth in the line of succession to the British throne.
On 30 December 2014, a Florida court filing by lawyers Bradley J. Edwards and Paul G. Cassell alleged that Andrew was one of several prominent figures, including lawyer Alan Dershowitz and “a former prime minister”, to have participated in sexual activities with a minor later identified as Virginia Giuffre (then known by her maiden name Virginia Roberts), who was allegedly trafficked for sex by Epstein.
Giuffre asserted that she had sex with Andrew on three occasions, including a trip to London in 2001 when she was 17, and later in New York and on Little Saint James in the U.S. Virgin Islands.
