Andersen has described William as able to intimidating eruptions regardless of his polished public demeanor.
He mentioned: “William is able to nice bellowing tantrums.”
In his e book, Andersen wrote the prince is usually respectful towards palace employees and strangers and by no means directs his mood towards his spouse, Catherine, Princess of Wales, 44, or their kids, Prince George, 12, Princess Charlotte, 11, and Prince Louis, eight.
Nonetheless, the creator claimed William has repeatedly raised his voice throughout arguments with Charles.
A former Highgrove employees member quoted within the e book mentioned “when he will get pissed off, (William) does resort to shouting” on the king.
The staffer added: “William has an enormous, booming voice. A lot louder than his father’s, so it is not one thing you quickly overlook.”
