Prince Harry reportedly decided to attend the King's Coronation a month ago but delayed confirming it publicly as he had some demands for his children.
A former equerry, who is close to both Harry and his brother Prince William, said he was aware of the Duke of Sussex's plans at the beginning of last month.
It has been claimed that one of the main reasons why Harry delayed confirming his attendance was that he wanted some recognition by the Royal Family for his children Archie and Lilibet.
