Buckingham Palace has said any suggestion Prince Andrew was involved in "impropriety with under age minors is categorically untrue" after he was named in US court documents.
A woman has reportedly alleged in a court papers filed in Florida that she was forced to have sex with the Duke of York when she was 17, which is under the age of consent in the state, according to the Guardian.
The woman claims she was made to "have sexual relations with this prince when she was a minor" in London, New York and on a private Caribbean island owned by Jeffrey Epstein, an American billionaire convicted of soliciting a minor for prostitution.
The claim is part of a lawsuit in connection with Epstein.
The Palace said it would not comment on ongoing legal proceedings.
"This relates to long-standing and ongoing civil proceedings in the United States, to which the Duke of York is not a party," a Buckingham Palace spokeswoman said.
"As such we would not comment on the detail. However, for the avoidance of doubt, any suggestion of impropriety with under age minors is categorically untrue".
