Still, reports have surfaced suggesting that Prince William was displeased by the gesture. One insider told the Daily Beast: “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.”
But can Prince William really take away their titles?
Royal expert Richard Fitzwilliams offered insight to Royal Insider, outlining the challenges involved.
“In theory he could, but it would cause enormous trouble and controversy,” he said. “It would need an act of Parliament to take away the Sussex dukedom which almost certainly won’t happen.”
“They shouldn’t use the HRH but we know they do. However he will always be a prince and she is a princess. The matter is best left.”

So, what titles do Harry and Meghan currently hold?
The couple remain the Duke and Duchess of Sussex — titles conferred on them by the late Queen Elizabeth II on their wedding day in May 2018.
Despite stepping away from official royal duties, they’ve retained their Sussex titles. In addition, they also hold the titles Earl and Countess of Dumbarton, as well as Baron and Baroness Kilkeel.
