LONDON — Andrew Mountbatten-Windsor was arrested on his 66th birthday in February on suspicion of misconduct in a public office. He is accused of passing sensitive government information to Jeffrey Epstein while serving as a government trade envoy.

Mountbatten-Windsor denies wrongdoing. The allegations stem from an archive of more than 30,000 emails handed to the lord chamberlain—the most senior officer in the royal household—in May 2020. Those messages, obtained from the account of British businessman Jonathan Rowland, an associate of Mountbatten-Windsor, appeared to show that he shared confidential information during his tenure as a trade envoy.

The emails were reportedly taken during a dispute between Rowland and an unnamed colleague and were later obtained by Kevin Stanford, the former majority owner of the fashion chain All Saints, during a separate disagreement over investments in the failed Kaupthing Bank. Jonathan Rowland confirmed that the messages had been obtained from his account as part of legal proceedings.

The full contents of the emails are unknown, but they are understood to contain correspondence dating up to June 2013. Emails obtained by The Telegraph showed Mountbatten-Windsor shared details of a Treasury briefing with Rowland, writing, “Before you make your move.” The newspaper reported in 2024 that Mountbatten-Windsor had requested confidential information from the Treasury in 2010 about the financial crisis in Iceland.

Authorities in Monaco and Luxembourg were also informed about the email archive. A spokesperson for the palace said it was “not possible to provide any comment on these matters” due to the “ongoing police inquiry.”

Thames Valley Police issued a fresh appeal for information regarding Mountbatten-Windsor and indicated it could investigate any allegations of sexual misconduct, including a claim that he behaved inappropriately at Royal Ascot.

Mountbatten-Windsor’s fall from grace followed a 2019 interview on BBC’s Newsnight, in which he failed to apologise for his friendship with Jeffrey Epstein. During the interview, presenter Emily Maitlis asked him about allegations made by Virginia Giuffre, who claimed she had been trafficked by Epstein to be abused by Mountbatten-Windsor. Mountbatten-Windsor denied the allegations and claimed not to have met her. He paid Giuffre an out-of-court settlement in 2022, thought to be worth about £12 million.
