Prince William to strip Prince Harry and Meghan Markle of their HRH titles when he becomes king: Source

LONDON, UK: Prince William will not allow Meghan Markle and Prince Harry to use their HRH (His/Her Royal Highness) titles once he becomes the king, sources have revealed.
A royal tipster told the Daily Beast, “Charles might be happy to put up with this, but William won’t.”

Buckingham Palace ordered Meghan Markle cannot use ‘Her Royal Highness’
Prince William “loathes and despises Harry and Meghan with every bone in his body; he believes they have betrayed everything the family stands for, and the idea that they are using their royal status as a calling card will enrage him,” the insider claimed.
The insider stated that Meghan’s disrespecting an agreement with the late Queen Elizabeth II as she continues to write ‘Her Royal Highness’ while promoting her brand, As Ever.
After joining Jamie Kern Lima for a podcast interview, she gave her a gift basket, containing “homemade strawberry sauce”, and a note with it read, “With the Compliments of HRH The Duchess of Sussex.”

However, as per a January 2020 statement from Buckingham Palace, “The Sussexes will not use their HRH titles as they are no longer working members of the Royal Family.”
It also shared that, “with The Queen’s blessing, the Sussexes will continue to maintain their private patronages and associations. While they can no longer formally represent The Queen, the Sussexes have made clear that everything they do will continue to uphold the values of Her Majesty.”

Meghan Markle accused of showing how weak King Charles is
Now, a friend of the future king has said, “Charles has completely lost control. It’s apparent that Harry and Meghan have every intention of making his final years a misery, just as he feared they would.”
“Meghan using her HRH exposes how weak and enfeebled he is. She knows he won’t do anything. There is no way King William will stand for this. The titles will simply be removed when he is king. A way will be found,” the pal noted.

But a source close to Meghan has denied the accusations.
Meghan and Harry not allowed to use royal titles ‘for commercial purposes’

They told the Daily Beast, “Harry and Meghan retain their HRH titles; however, by agreement, they do not use them for commercial purposes. While they do not publicly use ‘HRH,’ this was a personal gift, and their titles remain.”
A former courtier, however, called it “complete rubbish,” and claimed that their exit terms “made it clear they had agreed not to use the HRH titles at all, ever, in any capacity.”
Meghan and Harry left the royal family in 2020 to start a new life independently and have since then lived on a sprawling estate in Montecito with their two children — Prince Archie, 5, and Princess Lilibet, 3.
