Prince William and Prince Harry’s feud started when they were still young boys. But the latter’s relationship with Meghan Markle made things worse.

In the book Brother & Wives: Inside the Private Lives of William, Kate, Harry and Meghan, royal author Christopher Andersen revealed that Prince William and Prince Harry once got into a screaming match.

The harrowing incident took place after Prince William expressed his concerns over Prince Harry’s desire to propose to Markle. At the time, the Duke and Duchess of Sussex had only been dating for over a year.

Prince William urged Prince Harry to reconsider his decision because the future king believes that he needs more time to get to know Markle.

The Duke of Cambridge waited years before he proposed to Kate Middleton. In fact, the latter was teased for waiting for a decade before Prince William got down on one knee and proposed.

But there’s no denying how different Prince William and Prince Harry’s personalities were. So, when the former questioned the latter’s decision to get engaged, Prince Harry reportedly screamed at his brother at the top of his lungs.

The siblings’ feud became more worse after Prince William involved their uncle, Earl Spencer into the mix. According to Andersen, Princess Diana’s brother also had reservations about Prince Harry and Markle’s relationship and he shared his thoughts with his nephew.

However, Prince Harry didn’t also appreciate how his uncle doubted his relationship with Markle. So, he and his wife decided to push through with their wedding.

After the couple announced their engagement, they sat down for an interview and acted as though everything was going well within the royal family.

Months later, Prince William served as Prince Harry’s best man at his royal wedding even though he had qualms about his marriage to Markle.

But the brothers’ then-secret feud was eventually exposed when Prince William and Markle’s differences became even more glaring.

In the book Finding Freedom, author Omid Scobie said that Prince William and Markle never got the chance to be close. And the same can be said about Markle and Middleton’s relationship.

Scobie stressed that the tensions have always been between Prince William and Prince Harry and not their wives. But the public thought that Middleton and Markle were the ones that had an issue because they never developed a close bond.
