Buckingham Palace stepped up its denial that Prince Andrew had sex with an underage girl introduced to him by a disgraced U.S. financier, and named the alleged victim whose anonymity was preserved in court documents filed last week.

Last Friday Buckingham Palace denied allegations made in Florida court documents by the woman, who said she was forced as a minor by financier Jeffrey Epstein to have sex with several people, including Prince Andrew, the second son of Queen Elizabeth II.

Another of those named by the woman, well-known American attorney Alan Dershowitz, said he has assembled a team of "eminent" lawyers to fight the sexual abuse allegations made against him in last week's filing in Florida federal court.
