Royal author Tom Bower claimed the Duke and Duchess of Sussex wanted to appear next to the Queen on the balcony of Buckingham Palace during the celebrations. According to the biographer, Harry requested “the Queen’s unruly advisers” and when this “failed”, he visited the monarch on his way to the Invictus Games in The Hague in April.
However, Bower said the issue of the Sussexes stepping onto the palace balcony “remained unresolved”.
In Revenge: Meghan, Harry and the War Between the Windsors, he wrote, “The danger of allowing the gathering surfaced six days later.”
In the excerpt of his new book in The Times, Mr Bower said Harry and Meghan mixed “flawless” with athletes at the Games.
He added: “But, as later events seemed to show, their anger was that the palace had rejected all their demands for a prominent role at the jubilee in exchange for returning to Britain with their children.
“Harry couldn’t help but express his anger at an American NBC TV reporter.”
In the interview for NBC’s Today show, the Duke caused a backlash for saying he wanted to make sure the monarch was “protected” and had the “right people around.”
Mr Bower said: “Within those few minutes on television Harry had demonstrated the danger of his appearance at the jubilee celebrations.
“Everything revolved around him and Meghan.”
