Constitutional expert Iain MacMarthanne told Express.co.uk: “Like his great-grandfather, grandfather and mother before him the Prince of Wales when he becomes king will, in consultation with the prime minister and cabinet of the day, be able to amend, change and determine who enjoys the style and title HRH and prince or princess.
“Whether this happens, and who it might affect, only time will tell.”
According to Mr MacMarthanne, Archie is likely to assume a title despite Harry and Meghan’s step down as working royals.
He said: “As things presently stand, and irrespective of his parents withdrawal from front line royal duties, Archie Harrison Mountbatten-Windsor, otherwise the Earl of Dumbarton, and upon the accession of his grandfather HRH Prince Archie of Sussex, unless the Queen determines otherwise in the meantime, is, by courtesy, an earl, and will become an HRH and Prince.”
