Not only on St George's Day (the festival of England's Patron Saint) but also, historically, the first baby boy born in the Line of Succession to the British Throne after the introduction of the Succession to the Crown Act in 2015 to who hasn't, from birth, displaced his elder sister in the list. HRH Princess Charlotte of Cambridge remains in 4th place.
Equally, HRH The Prince Andrew, Duke of York would not be required to seek the permission of The Queen to remarry should he wish to as he is now 7th in line to the Throne and only the top six are required to.
The next thing will be his name(s). Many think it might be Arthur and many think Philip would be appropriate as well. Maybe a nod to the Duchess' father and Michael. We shall see.
Then, in 18 years' time, there should be a new Label. But first, there's the matter of a certain Royal Wedding...
UPDATE: We all know now that the new Prince has been named Louis Arthur Charles.
