Prince William is "still holding a grudge" against the Sussexes, expert claims

It sounds like there's still trouble in the House of Windsor.

The events around the Queen's funeral could have been an opportunity for the now-Waleses and the Sussexes to make up once and for all, but there was too much resentment among family members for it to make much of a difference in the end, one royal expert claims.

Speaking on the To Di For Daily podcast, hosted by Kinsey Schofield, biographer Christopher Andersen addressed the controversy about Prince Harry originally not being allowed to wear military uniform for funeral proceedings.

"In the very beginning, Harry was not allowed to wear his uniform — this was in the early days of the mourning period — but Andrew was and Edward was," Christopher said (via Express).

"So obviously, there was an outcry as a result of that. Charles flipped and allowed him [Harry] to wear his uniform at the vigil of the grandchildren. But it never looked to me as if the Sussexes were comfortable during the funeral — they could hardly wait to get out."

Somewhat dramatically, Christopher added: "And of course, I think William is still holding a huge grudge." 

In this case, he was referring to William feeling hurt over Harry and Meghan's decision to leave royal life and move to California.

As for the engagement both royal couples undertook together, a walkabout in Windsor following the Queen's death, Christopher doesn't think it was a true success.

"There was no connection," he said. "They were all going in different directions. I don’t think it’s going to end well."

He added: "If there ever was a chance for them to mend things, I suppose that was it. But then again, this book is hanging over everyone's head."

By "this book," Christopher means Harry's upcoming memoir, titled SPARE, which is set for release on 10 January. The book has been the subject of huge amounts of controversy in the months leading up to its publication, with royal insiders seeming concerned about what it could contain. 

As for the rest of us, we'll just have to wait till January to find out.
