Feud at Diana’s grave: Prince William and Prince Harry split over mother's 30th death anniversary films

The 30th anniversary of Princess Diana’s death may reignite one of the monarchy’s most bitter rivalries. According to royal expert Tom Sykes, Prince William and Prince Harry could be planning competing documentaries on their late mother—threatening to turn her legacy into their latest battleground.

Speaking on The Daily Beast podcast, Sykes revealed that he’s heard “on good authority” that the brothers, who have not spoken in years, are exploring separate projects to commemorate Diana in 2027. William is reportedly “not remotely amused” by whispers that Harry and Meghan Markle are working on a Netflix feature tied to their Archewell deal—especially after previous projects were panned as “boring” and “disastrous.”


“We could have dueling Diana documentaries from the two boys,” Sykes suggested, noting how such films could cement their clashing narratives about the princess’s life and the events surrounding her 1997 death.

The timing comes as Sykes himself stirs controversy with a fresh essay revisiting conspiracy theories about Diana’s fatal Paris car crash, raising questions about whether her death was as straightforward as official inquiries concluded. While he stops short of calling for the case to be reopened, Sykes insists “the holes in the story are just so fascinating, it’s all hidden in plain sight.”

Diana was killed on August 31, 1997, when a Mercedes driven by Henri Paul crashed in a Paris underpass. Paul and Diana’s companion, Dodi Fayed, also died. An official investigation blamed speed and Paul’s intoxication, but speculation about foul play has never fully disappeared.

Now, as the brothers approach this milestone anniversary on opposite sides of the Atlantic, Diana’s memory risks becoming collateral damage in their fractured relationship.
