The issue over Andrew’s friendship with Epstein has continued to dog the royals.
The King stripped his younger brother of his prince title following weeks of intense pressure over his links to the paedophile financier.
He is also expected to shortly move out of his Windsor mansion, Royal Lodge.
It came after Andrew Mountbatten-Windsor – as he is now known – gave up his other royal titles, including the Duke of York, after more questions and allegations about his private life.
At the start of this year, emails showed that he had stayed in contact with Epstein for longer than he had previously admitted.
In a posthumous memoir published in October, Virginia Giuffre – a prominent accuser of Epstein – repeated allegations that, as a teenager, she had sex with Andrew on three separate occasions. Andrew has always strenuously denied the claims.
Andrew has also faced calls from Democrats in the US Congress to give evidence to a committee investigating Epstein’s activities. He had not replied to the request by the end of their deadline last month.
Separately, two photos of Ms Ferguson – then the Duchess of York – have emerged in the document dump.
One shows her standing on a pavement next to an unidentified woman holding a shopping bag. In the other, she is sitting cross legged on a green sofa.
