Andrew Mountbatten Windsor's prince title and HRH style have been formally removed by the King.
Details of the Letters Patent have been published by the Crown Office in The Gazette, the UK's official public record.
The entry read: "THE KING has been pleased by Letters Patent under the Great Seal of the Realm dated 3 November 2025 to declare that Andrew Mountbatten Windsor shall no longer be entitled to hold and enjoy the style, title or attribute of 'Royal Highness' and the titular dignity of 'Prince'."
Charles's decision to effectively banish Andrew from the monarchy, removing his birthright to be a prince, as well as his dukedom, followed growing controversy over his links to paedophile financier Jeffrey Epstein.
For many years, Andrew has been dogged by allegations he sexually abused Virginia Giuffre after she was trafficked by the financier.
He has strenuously denied the allegations.
Andrew stepped down from public duties in 2019 after his disastrous Newsnight interview about his friendship with Epstein and as a non-working royal does not serve as a counsellor of state, who can deputise for the monarch if he is overseas on an official trip or ill.
Letters patent are a type of legal document and an "open letter" which expresses the will of the Monarch, usually on ministerial advice.
There are dozens of different types of letter patents, including creating life peerages, granting city status or conferring royal titles, according to the House of Commons library.
