Under the influence of his opinionated wife, Meghan, who turns 38 in August, Harry has ripped up the royal rule book and is determined to do things his way.
First, he and Meghan riled the press and some fans by keeping the birth of their new son private, and gave out false information about where and when he was born.
Then they named him Archie Harrison and didn’t give him a title or ask the Queen to make him a prince.
Next they applied for further planning permission to extend their home, Frogmore Cottage at Windsor, at taxpayer’s expense.
They also decided to end their partnership with William and Kate and split from
their joint charity the Royal Foundation, fuelling rumours the brothers and their wives don’t get on.
And during the state visit by Donald Trump, Harry was notably absent from the evening banquet, and kept his distance from the US President at a palace lunch, clearly annoyed that he had called Meghan “nasty”.
“Harry needs to grow up and take a leaf out of the Queen’s book,” said one senior courtier.
“She has often had to entertain people she doesn’t like, but she would never let her feelings interfere with the job.
“There are fears Harry is becoming too precious and sensitive to criticism.”
Royals author Ingrid Seward told me: “Harry is behaving in an immature way and letting his personal animosity take over from his natural good manners. You have to think Meghan is influencing him behind the scenes and this could be dangerous.
“His duty is to support the Queen and the institution, and sometimes that means gritting your teeth and doing things you don’t like.”
