Andrew Mountbatten-Windsor, 66, has been arrested on suspicion of misconduct in public office.
Six unmarked cars pulled up to Wood Farm on the royal Sandringham Estate shortly after 8am on Thursday, his birthday, and plain-clothes officers walked him into custody in what is believed to be the first arrest of someone this close to the Crown in the modern era.
The allegation is specific: that the former prince, stripped of his royal titles last October,passed confidential government documents to the late convicted sex offender Jeffrey Epsteinduring his decade as a UK trade envoy.
Thames Valley Police confirmed the operation but did not name the arrested man.
'As part of the investigation, we have today arrested a man in his sixties from Norfolk on suspicion of misconduct in public office and are carrying out searches at addresses in Berkshire and Norfolk,' the force said.
That is standard police phrasing. It does not usually land like a constitutional earthquake.
The US Department of Justice released more than 3.5 million pages of Epstein-related documents on 30 January 2026, and buried in that mountain of files were emails that appear to show Mountbatten-Windsor forwarding official British trade reports to Epstein within minutes of receiving them from his own adviser. The visits covered Singapore, Hong Kong and Vietnam; the emails date to late November 2010, when the former prince was still serving as the UK's special representative for trade and investment, a role he held from 2001 until his resignation in 2011.
Republic, the anti-monarchy campaign group, called for a formal police investigation earlier this month. Thames Valley Police acknowledged barely a fortnight ago that it was assessing the complaints.
Whether Mountbatten-Windsor expected the inquiry to move at this pace is anyone's guess. The speed suggests the evidence was already rather difficult to set aside.
Misconduct in public office is an old common-law offence. It carries a maximum sentence of life imprisonment.
