Prince Charles and Prince Andrew are difficult to manage due to their temper and attitude.

The Prince of Wales and Duke of York weren’t close growing up. Just recently, Prince Andrew spoke about the Epstein scandal and many believed that Prince Charles will give him his stern words when the heir apparent returns from his royal tour.

According to royal biographer Penny Junor in her 2005 book “The Firm,” both of the princes are difficult to manage. Prince Charles has a “fearsome temper” while Prince Andrew has a “childish and stupid” attitude.

“The Prince of Wales is a difficult man to advise,” Junor wrote.

Unfortunately for Prince Charles, the palace is filled with advisers and courtiers. The advisers are professionally employed to give impartial advice. Meanwhile, the courtiers want to keep their job and usually tell the principal person what they want to hear.

“The Prince of Wales didn’t want to hear impartial advice; he wanted to hear people agreeing and he’s always been a bit like that. The Prince of Wales has a fearsome temper,” Junor added.

On the other hand, the royal expert added that she never saw Prince Andrew furious. However, the press secretary had reportedly never woken him up for breakfast because the duke could be moody.

According to Ryan Parry, the undercover butler in Buckingham Palace, depending on Prince Andrew’s mood he would either say “good morning” or “[explicit] off.”

Junor added that she wanted to believe that Parry was just making up the story, but she also suspected that it was true. She recalled an incident when Prince Andrew confronted Prince Charles’ staff for not telling him that he was attending a black tie dinner after realizing that he was the only one not properly dressed. Prince Andrew reportedly told the staff that they were in trouble.

“It was childish and stupid and his office had been told,” Junor said of the Duke of York.

In related news, Emily Fairbaim of The Sun believed that it was Prince Andrew’s signature arrogance that prompted him to push with his controversial interview with the BBC despite being advised against it. Fairbaim said that maybe Prince Andrew thought he would be charming enough to convince the public since he denied the allegations that he slept with teenager Virginia Roberts. However, in reality the move only backfired because “charm has never been the prince’s strong suit.”
