An image of Andrew Mountbatten-Windsor and Peter Mandelson with the paedophile Jeffrey Epstein has been found in documents released by the US Department of Justice (DOJ).
It is the first known image of the three men together, but no time or location is given for the photograph.
ITV News said the photo was takenin Martha's Vineyard in the US and is believed to have been taken between 1999 and 2000, before Epstein was sentenced to 13 months in prison and registered as a sex offender.
The image shows the men sitting around a wooden deck table, with mugs decorated with the US flag in front of them. There is no suggestion that appearing in the documents implies any wrongdoing.
Mountbatten-Windsor and Lord Mandelson have separately been arrested on suspicion of misconduct in public office over their connections to the paedophile and have both since been released under investigation.
Mountbatten-Windsor has repeatedly denied any wrongdoing in relation to Epstein.
Lord Mandelson has repeatedly let it be known that he believes he has not acted criminally. He has long argued that he accepted Epstein and his lawyer's version of events and only discovered the truth after his death in 2019.
Mountbatten-Windsor has said he first met Epstein, in 1999 through Ghislaine Maxwell, Epstein's British girlfriend, who he had known since she was at university.
Their connections to the late financier have seen both men lose positions, with Mountbatten-Windsor stripped of his royal titles and Lord Mandelson sacked as the UK's ambassador to the US.
Mountbatten-Windsor has been accused of having sex withVirginia Giuffre when she was a teenager. A civil case brought by Giuffre was settled with no admission of guilt, and he has strenuously denied the allegations.
The BBC has seen the newly discovered image in the latest tranche of documents, which was part of three million pages, 180,000 images and 2,000 videos posted publicly by the DOJ in January.
Material is still being discovered as journalists and the public continue to look through the files.
Earlier this year,photographs appearing to show Mountbatten-Windsor kneeling on all foursover a female lying on the ground were released in a new tranche of US documents.
In two of the images he is seen touching the person, who is unidentified and fully clothed, on her stomach. Another image shows him staring directly at the camera.
He has consistently and strenuously denied any wrongdoing.
