Prince William and Prince Harry’s Uneasy Truce Faces Fresh Test Over Emotional Diana Project

Prince William and Prince Harry’s fragile uneasy truce could face a fresh test over how they honour Princess Diana project, as speculation grows that the Duke of Sussex is considering a documentary to mark the 30th anniversary of their mother’s death.

The estranged brothers have not publicly shown signs of repairing their relationship, but both have continued to honour Diana’s memory through charitable causes and personal tributes without directly interfering with each other’s approach.

That delicate arrangement could become more complicated as the 2027 anniversary approaches, particularly if Harry moves forward with reported plans for a documentary exploring Diana’s life and legacy.

Royal expert Richard Palmer said both brothers want to honour their mother “in the most meaningful way,” despite the deep personal differences that have developed between them over recent years.

Palmer also recalled that William previously resisted attempts to portray the brothers as competing over Diana’s legacy and was “always at pains” to reject efforts to pit one son against the other over who carried their mother’s torch.

However, The Sunday Times has reported that William previously turned down an opportunity to participate in a Diana documentary after being approached by Netflix.

Harry, meanwhile, has been linked to a separate potential project, with reports suggesting he has approached people who knew Diana as he considers ways to commemorate the anniversary.

Their uncle Charles Spencer has also indicated that one of his nephews is interested in making a film, although he did not identify whether he was referring to William or Harry.

Royal expert Jennie Bond believes Harry has every right to pursue such a project but warned that it could create another sensitive issue between the brothers.

“Harry obviously has every right to mark the anniversary of his mother’s death in any way he sees fit,” Bond said, adding that there would undoubtedly be significant public interest in another documentary about Diana.

“I’m sure the world would love to see another documentary about Diana, once the most famous woman in the world who remains an icon for many,” she continued.

Bond predicted that William would probably avoid publicly responding if Harry eventually releases a documentary, pointing to the Prince of Wales’s silence through previous family controversies, including the recent claims made in Earl Spencer’s memoir.

However, the expert warned that a film could further deepen the brothers’ estrangement rather than bring them together around their shared love for Diana. Neither Harry nor his representatives have formally announced a documentary, while William has not publicly criticised the reported idea.

With the anniversary still ahead, the brothers are not yet confirmed to be competing over any Diana project. But if Harry proceeds while William chooses a quieter commemoration, their contrasting approaches could once again place their fractured relationship under intense scrutiny an outcome Bond suggested would be far removed from the family unity Diana would have wanted for her sons.
