Mountbatten-Windsor is the personal surname of some of the descendants of Queen Elizabeth II and Prince Philip, Duke of Edinburgh under a Declaration made in Council in 1960. However, although the declaration specifically applies the name "Mountbatten-Windsor" to male-line descendants of the Queen not holding Royal styles and titles, "Mountbatten-Windsor" has been used by some descendants of the Queen who do hold Royal styles. This is presumably on the basis that the 1960 declaration is argued to confer a "hidden surname" in such cases. For example, each of Prince Andrew, Duke of York and Anne, the Princess Royal, children of the Queen, used the surname "Mountbatten-Windsor" in official marriage registry entries. Likewise, the Duke and Duchess of Cambridge used the name when filing a French lawsuit related to the topless pictures of Catherine published by the French magazine Closer.
