Prince William reportedly warned his younger brother, Prince Harry, about moving too quickly in his relationship with Meghan Markle, according to Fox News.

“Battle of Brothers: The Inside Story of a Family in Tumult” claims, “The fundamental conflict was between the two males who had known each other all their lives and had never hesitated to tell each other exactly what they thought and felt.”

“William worried that his brother was moving too fast in his courtship — and he did not shrink from saying as much when Harry started talking about getting hitched to Meghan quite soon.”

“William couched his question in terms of apparent concern for Meghan,” Lacey wrote.

“’Waity William,’ of course, took so long to commit to Kate [Middleton] for the sake of the monarchy.”

“He had been auditioning her for a job all those years. So Harry could not help but wonder whether Will was really concerned about his personal happiness — or whether he was, once again and as per usual, thinking about the makeup and fortunes of ‘the Firm’ whose boss he would become one day?” said the author, per People.

“The response from Harry was a brusque and offended pushback.”

“Here we have a couple of brothers who loved each other dearly — most profoundly and genuinely, in fact — but who could give as good as they got when it came to a clash over something that mattered intensely to them,” wrote the historian.

“For William it was the future state of his monarchy — his sacred trust; while for Harry it was the love of the complex and captivating woman who had finally made sense of his life.”

The author claimed that a “confrontation” occurred between the royals in “late 2016 or early 2017” in regards to Harry’s desire to marry Markle.

After Harry and Markle wed in 2018, it seemed that he would work alongside his brother and his wife, Kate Middleton, but it soon became clear that would not be the case.
