King Charles is reportedly undecided over whether his two youngest grandchildren - Archie and Lilibet - can use their titles of prince and princess and their HRH stylings.
Prince Harry and Meghan Markle have caused a stir in recent weeks after the release of their controversial six-part Netflix's docuseries, where they have made several claims against the Royal Family.
Three hour-long episodes were initially on Thursday, December 8 with three more hours of footage released this week on the streaming website as the Duke and Duchess of Sussex look to convey their side to the story which led them to leaving their roles as working royals in January 2020.
In the second part of the docuseries, Harry claimed at a family gathering to decide the couple's future in the institution, William shouted and screamed at him while King Charles told lies as the late Queen sat there and listened.
Despite Harry and Meghan stepping away, their children Archie, three, and Lilibet, one, became a prince and princess when Queen Elizabeth II died in September.
The Queen's death saw the Sussex children move up in the line of succession and as the grandchildren of the new monarch they have a right to HRH status.
The children and grandchildren of a sovereign have the automatic right to the title HRH and prince or princess due to protocols created by King George V in 1917.
King Charles will have to issue a Letters Patent to change Archie and Lilibet's status if he decides to scrap their titles in line with his vision for a slimmed down monarchy.
The Sunday Times understands that the monarch will not make a decision on if his grandchildren can use their royal titles and HRH stylings until after the release of Prince Harry's forthcoming memoir.
Harry's much-anticipated autobiography 'Spare' is expected to be released on January 10, 2023 and could bring more scrutiny on the Royal family if there are more accusations and claims in the 416-page memoir, which he reportedly earned $20 million in advance to produce.
A source close to the King, told the Sunday Times: “Let’s wait and see, no final decisions have been made.” Buckingham Palace also declined to comment.
It is reported that King Charles will still invite the Duke and Duchess of Sussex to his coronation in May next year despite the revelations from the couple who moved to California after stepping back from royal duties.
His Majesty is said to have told Harry and Meghan they are welcome to attend the event as he does not want his coronation to be side-tracked by drama.
The source told the Daily Mail: "Harry is his son and His Majesty will always love him. While things are difficult at the moment, the door will always be left ajar."
However, Harry and Meghan reportedly want the Royal family to apologise to them before they attend the King’s coronation.
Harry and Meghan want a face-to-face meeting to address the claims they raised in their £88million Netflix series. The Sussexes are said to want The Firm to 'take responsibility' for the pain and damage they put the couple through.
