Queen Elizabeth II took over Prince William job due to lack of King Charles ‘attention’

Queen Elizabeth II personally over saw the upbringing and training of her favourite grandchild.

Her Majesty was seemingly concerned about Prince William, the importance of his role in the Royal Family and this wanted to ensure he was brought up right.

Writing in his biography, William and Catherine: The Monarchy's New Era: The Inside Story, royal expert Russell Myers says: "As a result of Diana's growing influenceover her children and, at the time, Charles's lack of it, The Queen set about subtly constructing her own authority over the future King.”

“Together with Charles, she delicately introduced William to the concept of his destiny, while also making clear that the family was supposed to be dedicated to its people and not to serving one's own purposes,” he added.

"The Queen Mother, in particular, doted on William, sending him small gifts and letters of encouragement throughout the years, and early on became the biggest enforcer of William's concept of his destiny," per Myers.

Myers continued: “During family occasions, the Queen Mother would insist William be seated beside her, further reinforcing his position as heir and sowing the seeds of the unspoken difference between him and Harry."
