There appear to be several definitions of Working Royals, for example if it is those who undertake engagements on behalf of the Queen, it would not include her granddaughters, ( though they currently do not undertake official engagements) but would include some of her cousins. If it is the Queens direct descendants the cousins are not included. Then of course there is the way Charles sees it. Although it is very doubtful that Harry and Meghan will return on any official footing,I think we must wait until we have official confirmation of this, and even then I don’t think Harry will renounce his and Archie’s position in the line of succession. The whole thing is a minefield, which more than likely, in the future, Charles will have to sort out.
Anniebach as it stands at the moment do we assume the eight to which you are referring consists of The Queen, The Prince of Wales and the Duchess of Cornwall, the Duke and Duchess of Cambridge, Princess Anne and the Earl and Countess of Wessex, with others put into retirement?
