Overview
- Royal sources confirmed the former prince will be styled Andrew Mountbatten-Windsor going forward, correcting the initial non-hyphenated form announced in late October.
- The palace’s first wording — reportedly agreed with Andrew as his preference — omitted the hyphen, prompting surprise from historians who cited longstanding precedent.
- Queen Elizabeth II’s Privy Council declaration, published in The London Gazette in 1960, set Mountbatten-Windsor as the surname when a royal surname is required for those without princely styles.
- Official records and listings have long used the hyphenated form, including Princess Anne’s 1973 marriage register and the birth registration of Archie Mountbatten‑Windsor.
- The naming update comes as administrative steps continue to redefine Andrew’s status, with formal notice served to surrender his Royal Lodge lease and plans for alternative private accommodation.
