Princess Diana’s Brother Has Made His Choice Between Prince William and Prince Harry, Royal Expert Claims
Ahead of the release of his revealing new memoir about Princess Diana, Earl Charles Spencer has reportedly made his loyalties clear in the ongoing royal rift between his nephews, siding strongly with Prince Harry over Prince William.
The startling claim was shared by prominent royal biographer Tom Bower during an interview on GB News, where he analyzed the motivations behind the 9th Earl Spencer’s upcoming book dedicated to his late sister’s life and legacy.

1. The Alleged Rift and Spencer’s Allegiances
According to Bower, the 62-year-old Earl’s personal stance toward the Royal Family has become increasingly polarized:
-
Siding with Harry: Bower stated directly that Spencer “doesn’t like William” and is “very pro-Harry,” noting that Diana’s brother remains deeply critical of the establishment.
-
Tensions with the Crown: The biographer added that Spencer remains “furious with King Charles” and continues to feel “awfully unhappy about how his sister was treated” during and after her marriage into the royal household.

Bower drew direct parallels between Spencer’s forthcoming work and the Duke of Sussex’s explosive memoir, Spare, cautioning that the new release could inflict further reputational damage on the monarchy.
2. Swan Song: Diana, My Sister
The Earl’s new book, titled Swan Song: Diana, My Sister, is scheduled for release next month. While acknowledging Spencer’s undeniable skill as a writer and his unique insider perspective, Bower raised questions regarding the tone of the upcoming account.
“Harry’s book was filled with absolute untruths and fabrications,” Bower remarked, expressing hope that Spencer’s work will offer an authentic, balanced portrayal of Diana’s tragic journey rather than turning into a vindictive settling of scores.
3. Setting the Record Straight Ahead of the 30th Anniversary
Explaining his decision to write the book, Earl Spencer issued a public statement addressing the relentless media attention surrounding his sister.
-
Inundated with Requests: With the approaching 30th anniversary of Princess Diana’s passing, Spencer noted he had been overwhelmed by interview requests seeking his perspective.
-
Correcting Accepted Misconceptions: Spencer stated that putting his own memories on paper once and for all was preferable to “the discomfort of again reading the opinions of others, many of which are based on untruths that have become accepted over time.”
As Swan Song: Diana, My Sister prepares to hit bookshelves, Earl Spencer’s firsthand account promises to offer an intimate look into Diana’s life, while reigniting high-stakes discussions surrounding the ongoing divide within the British royal family.
