Queen Camilla has demonstrated that it's possible to win back the public's favor, according to a royal expert.

There are rumors that Meghan Markle and Prince Harry want to return to the royal fold. However, there are mixed opinions about their potential comeback because the royal couple, now based in California, has been plagued with negative headlines after they trashed the royal family.

Royal expert Duncan Larcombe, award-winning journalist and former royal editor for The Sun for over 10 years, weighed in on the matter. According to him, the Duke and Duchess of Sussex still have a chance to reunite with the royal family.

"I think the Sussexes are aware the Prince and Princess of Wales are still furious, and Kate's name coming out in that book will have reignited William's anger," Larcombe told New Magazine, per GB News

"There's always a way back. Look at Camilla -- she was the most hated person in Britain, and now she's the Queen. If that's possible, anything's possible."

However, he also acknowledged that considering the things that happened recently, "it's pretty unthinkable." An unnamed source added that if the Sussexes wanted to reunite with the members of the firm, they should "not speak ill of the royals again."

"Meghan and Harry have to agree not to speak ill of the royals again. That's a must," another royal insider shared the same with Life & Style magazine. "It would be an utter embarrassment if they were to be kicked out of the family for a second time."

Prince Harry and Markle have maintained their silence about the controversial book "Endgame" that seemingly attacked the royals, despite the numerous people calling them out to deny the race row and distance themselves from Omid Scobie's publication. However, there have been various claims that they want to reunite with the royal family.

An insider told OK! magazine that Prince William's brother wants to spend Christmas in the United Kingdom because he has been "lonely" in California and received a lot of invitations from his pals in his home country.

Meanwhile, Prince Harry's biographer, Angela Levin, also said he wants to return to the royal fold. However, the "Harry: A Biography of a Prince" author was convinced that it was for another reason -- because "everything else he's done has failed."

"He wants to come back. He wants to be a member of the Royal Family again, but my goodness, he is a very changed Harry, and he's going to do what he wants," Levin claimed. "The fact that he has no respect for his father, no respect for his birth, I think he is going to be a big danger because he will go into competition with the Royal Family themselves."

While some are hopeful for the Sussexes' future with the royal family, British journalist, broadcaster and author Nichi Hodgson said Prince Harry has a chance but not Markle. According to Hodgson, the Brits might accept Prince Harry back if he divorced Markle because the people had a "distaste for her."
