Thomas Mace-Archer Mills, found of the British Monarchists Society spoke to The i newspaper about whether or not Tom and Laura would undertake royal duties now their mother is Queen Consort, and said it was unlikely.

He spoke exclusively: “There is definitely a very quiet distinction between who is in and who is out, even though they are one family because it is not right for the children of the spouse of the King who are not sired by him to be involved in the workings of the monarchy.

“Their mother Camilla is royal by marriage, but they are not. That seems a harsh way of putting it, but it is the truth. “They might be invited to functions now that their mother is going to be Queen [Consort], but they will not be undertaking any sort of official engagement or be asked to do anything which would mean them representing the British Crown. “It is only blood royals that can and will be representing the Crown. Even though they are inclusive in the family, they are not related to the Royal Family.”
