In a newly released biography entitled "Endgame: Inside the Royal Family and the Monarchy's Fight for Survival," royal expert Omid Scobie delves into the reported tensions between Prince William and Meghan Markle during her time in the royal family. According to Scobie, Prince William had reservations about the "opinionated" Duchess of Sussex from the very beginning of her relationship with his brother, Prince Harry.

Scobie's book sheds light on Prince William's concerns about the speed of Harry and Meghan's relationship, given her different upbringing and nationality. The Prince of Wales, according to Scobie, felt Meghan Markle was an "outsider" within the Firm, and her arrival into the royal family was perceived to have a negative impact on their image.

As claims of Prince William's alleged disapproval of Markle became apparent to others, tensions between the siblings escalated. Scobie alleges that Harry accused his brother of not making Markle feel welcome within the royal fold. Leaks from the palace further suggested that William "truly didn't like Meghan" due to her perceived "opinionated" nature.

The biography also highlights a shift in Prince William's attitude over the years. Scobie notes that William seemed to have a more carefree and jovial demeanor in the past, but as he took on more responsibilities, there was a noticeable change in his behavior, with a "harder" and "more worn-down" demeanor becoming apparent.

In addition to the revelations surrounding Prince William, Scobie discusses claims about his wife, Kate Middleton. According to the book, the Middleton family strategized to integrate Kate into William's life by encouraging her to attend St. Andrew's University instead of Edinburgh University. Scobie alleges that Kate underwent elocution lessons in order to refine her accent, which led to a perceived increase in her posh and "plummy" manner of speech.

While Kensington Palace has never denied Kate Middleton's elocution lessons, these claims further shed light on the efforts made to ensure her seamless integration into the royal family.

As the revelations from the biography continue to capture attention, it remains to be seen how the royal family will respond to these claims. The biography provides a behind-the-scenes look into the inner workings of the Firm and the alleged tensions that have plagued the family in recent years.
