He denied the allegations and emigrated to Israel.Like Edo's in-laws, Andrew Mountbatten Windsor and Sarah Ferguson, Ratner has been tainted by association with the late sex offender Jeffrey Epstein.Last year, a photo was released as part of the Epstein files which showed Ratner posing with Jean-Luc Brunel, one of Epstein's associates.Further images released in January showed Ratner on a sofa with Epstein and two young women. Ratner was cuddling one of the women in one of these photos.He appeared with Epstein, Brunel and three women in another picture.Ratner said he 'didn't have a personal relationship' with Epstein. He had met the financier only once, he said, and the woman he was pictured embracing was his then fiancée.Dara insisted that her relationship with Ratner is not romantic, telling Eden: 'We are only friends.'
