Royal Visit to the USA

[McClef]

Possibly, but that is by no means a given. All royal titles revert to the sovereign, who then determines what, if any, destination of that title will be allowed.

But do they? All royal titles that have had a direct male heir have been inherited by that heir without a new creation in the Peerage. Only when there is none or the holder succeeds to the throne do they revert to the Sovereign.

For example the Dukes of Kent and of Gloucester inherited theirs (conferred upon them by their father George V) from their fathers. York did not because the previous holder became King (George VI) and he had no male heirs to begin with. Prince Andrew the current Duke of York has no male heirs either. Interestingly this title has never been passed on since 1474 as previous holders have either died without male issue of ended up succeeding to the throne.

This line of argument presupposes that (1) the present Duke of Edinburgh outlives Her Majesty, and (2) that the letters patent creating HRH Duke of Edinburgh have not already received Royal Assent. As it was announced at the time when HRH Prince Edward received the title of Earl of Wessex that he would succeed his father as Duke of Edinburgh I suspect, as they say in Ireland, that "the fix is in".

There may be another "fix" but this one would be rather off topic
