The email, released by the US Department of Justice (DoJ), adds that “G Maxwell” was not aware of “anything improper” taking place at her home.

The name of the person has been redacted from the published version of the statement, but the details indicate that it is Maxwell who was discussing Giuffre.

Giuffre – a prominent accuser of Epstein and Maxwell – alleged Mountbatten-Windsor had sex with her three times as a teenager.

Mountbatten-Windsor, who has always denied the allegations, reached an out-of-court settlement with Giuffre in 2022. It contained no admission of liability or apology.

BBC News has approached Mountbatten-Windsor’s representatives for comment.

Last year, a July 2011 email from Epstein, published by Democrats on the US House Oversight Committee, also appeared to confirm that Mountbatten-Windsor was photographed with Giuffre.

The message sent by Epstein – who is alleged to have taken the photo – reads: “Yes she [Giuffre] was on my plane and yes she had her picture taken with Andrew.”

In a 2019 interview with Newsnight, Mountbatten-Windsor denied meeting Ms Giuffre and suggested that the photograph – or elements of it – may have been faked.

Mountbatten-Windsor said at the time: “Nobody can prove whether or not that photograph has been doctored but I don’t recollect that photograph ever being taken.”

In the disastrous interview, he also famously claimed he was not at Maxwell’s home but at a Pizza Express in Woking.

Speaking to BBC Newsnight on Wednesday, Giuffre’s sister-in-law, Amanda Roberts, said through tears that the release of documents from the so-called Epstein files has been a “whirlwind”.

“I’ve felt like a moment of such overwhelming emotion because I wish she was here to see this, she fought so hard and so long and she was still so strong”, she said.

Amanda added: “We’re proud of her and her accomplishments, but we miss her greatly in this moment, she should be revelling in this moment.”

In a statement to Newsnight earlier, the family said they were “hopeful that Andrew will face criminal charges”.
