Prince Andrew is to become Mr Andrew Mountbatten-Windsor

A statement from Buckingham Palace:-

His Majesty The King has today initiated a formal process to remove the Style, Titles and Honours of Prince Andrew.

King Charles has initiated the formal process to remove of the style, titles and honours of the former Prince Andrew, who will now be known as Andrew Mountbatten Windsor, Buckingham Palace announced Thursday, 30 October, 2025. 

I believe that the style and title of Prince and HRH can be removed by a Royal Warrant or Orders in Council, as in the case of Princess Patricia of Connaught, who was authorized by King George V in 1919 to cease using her styles and titles. She married into a Scottish aristocratic family and was styled as Lady Patricia Ramsay until her death in 1974. She did however retain her position as a member of the Royal Family and was in the line of succession to the throne, albeit distantly. In order to remove Andrew's dukedom, earldom and barony, an Act of Parliament will be required.  A titles deprivations Bill will now be drawn up and introduced into the the House of Commons, a debate and vote will follow, and the bill will progress to the House of Lords. With the backing of the Government and the full approval of the King this could be a speedy process. Whether this will be legislation specifically framed for Andrew, or new measures giving the monarch powers to remove peerages in general, remains to be seen. Similarly if it is desired to remove the disgraced royal from the Line of Succession and/or as a Counsellor of State, an Act of Parliament will be required. The status of Andrew's daughters is unaffected.

As the younger son of a duke (his father Prince Philip was of course Duke of Edinburgh) he would, by courtesy, be styled as Lord Andrew Mountbatten-Windsor. But all honours, including courtesy titles come from the Crown, and if the King has decreed that his brother is to end his days as "Mister" Mountbatten-Windsor - then so be it.

His lease on Royal Lodge has, to date, provided him with legal protection to continue in residence. Formal notice has now been served to surrender the lease and he will move to alternative private accommodation. These censures are deemed necessary, notwithstanding the fact that he continues to deny the allegations against him.

Their Majesties wish to make clear that their thoughts and utmost sympathies have been, and will remain with, the victims and survivors of any and all forms of abuse.
