British princess

A British princess is a princess who has the title of a Princess of the United Kingdom of Great Britain and Northern Ireland. In Britain, the title "Princess" and the use of the style "Royal Highness" can only be used for these persons:
Queen Elizabeth II issued Letters Patent dated 21 August 1996 stating that any woman divorced from a Prince of the United Kingdom would no longer be entitled to the style "Royal Highness". This has so far applied to Diana, Princess of Wales, and Sarah, Duchess of York.
