Andrew Mountbatten-Windsor and Jeffrey Epstein asked an exotic dancer to "engage in various sex acts" at the late convicted sex offender's Florida home, a legal letter claims.

In a letter released as part of the latest tranche of Epstein files, the unnamed woman's lawyers said she had been offered $10,000 to dance and that after she performed Epstein and Mountbatten-Windsor had asked for a threesome.

Lawyers said the woman had not been paid the promised amount and would keep the alleged 2006 encounter in which she was "treated like a prostitute" confidential in exchange for a payment of $250,000.

BBC News has contacted Mountbatten-Windsor for comment. He has always denied any wrongdoing.

The letter, dated March 2011, claims that the woman and other exotic dancers from "Rachel's Strip Club" in West Palm Beach had been chauffeured to Epstein's house and offered $10,000 to perform.
