An American lawyer, named alongside Prince Andrew in US court papers, says he has no knowledge of the Duke's relationship with the claimant Virginia Roberts.
Alan Dershowitz told ITV News: "I don't know what his relationship, if any, is with this woman.
"There is a photograph of him, there's no photograph of me. There's a diary with him, there's no diary with me.
"I hope if he is innocent, he can catergorically deny and make the same defence I'm making. But if he has anything to hide, obviously he's in a very different situation."
Mr Dershowitz, who is also a Harvard law professor, claims the woman is lying and says even according to her own account she was not underage at the time.
He added: "She claims she got paid for it. There's a word for that. She's admitting that she's been a prostitute."
