After Nearly 30 Years of Silence, Diana's Brother Will Publish a Memoir About Her

Charles Spencer, the 9th Earl Spencer, will publish a book about his sister Diana titled Swan Song: Diana, My Sister, with a UK release date of 22 September through the Penguin imprint Michael Joseph. According to the publisher, the book marks the first time Earl Spencer has spoken openly and at length about his sister (The Guardian).
Daniel Bunyard, publishing director at Michael Joseph, is overseeing the title's release. The imprint sits within Penguin's literary fiction and narrative non-fiction division, a positioning that signals the book is intended as a serious memoir rather than a celebrity memoir format.
Spencer's public voice on Diana has, until now, been defined by a single, searing moment. On 31 August 1997, Diana, Princess of Wales, died in a car crash in Paris. Days later, her brother delivered the eulogy at Westminster Abbey in September 1997, an address that drew a televised audience measured in the hundreds of millions and became one of the most replayed speeches in modern British public life. Spencer used the occasion to pledge that Diana's "blood family" would protect her sons, a passage widely interpreted at the time as an implicit rebuke of the Royal Household's handling of her public role and legacy.
In the years since, Spencer has largely kept his reflections on his sister within the boundaries of that eulogy and occasional public gestures. Last August, on the 28th anniversary of Diana's death, he brought flowers to her burial site at Althorp, the Spencer family estate in Northamptonshire (E! Online). The gesture was private and visually understated, consistent with a pattern of marking anniversaries without extended public commentary.
More recently, that reticence showed signs of breaking. During a podcast appearance in October 2025, Spencer revealed new details about his original eulogy for Diana, describing it as "very different" from the version he ultimately delivered at Westminster Abbey (People). He did not, at that time, publish the full text of the earlier draft. The podcast disclosure now reads, in retrospect, as an early signal of a broader willingness to revisit the public record of his sister's life and death on his own terms, in his own book, at his own pace.
The timing of Swan Song sits within a wider publishing and media landscape in which the Diana narrative has been continuously revisited across memoirs, documentaries, and dramatised series. What sets Spencer's contribution apart is his position as a primary witness, someone who was personally present for the events he describes, who has spent nearly three decades declining to give a sustained, extended account. The publisher's framing, that this is the first time he has spoken "openly and at length," sets an explicit expectation that the book will move beyond the eulogy's rhetoric into more granular personal territory.
What remains unknown is how far the book will travel into contested terrain. The 1997 eulogy itself touched on the relationship between Diana and the press, the Royal Family's institutional response to her popularity, and the question of her sons' upbringing. Whether Spencer addresses these subjects with new factual disclosures, or whether the book operates in a more reflective, elegiac register, is a question the September release will answer. The podcast appearance suggests at least some material will revisit the circumstances of the eulogy itself, potentially including the earlier draft.
The broader context here is about source material rather than sensational disclosure. Spencer is a first-hand witness to the final years of Diana's life, the immediate aftermath of her death, and the family dynamics that shaped the public response. His previous writings have focused on the Spencer family's broader history rather than on Diana specifically. Swan Song narrows that lens, and in doing so, adds a primary-source document, an account written by someone with direct knowledge of the events, to a historical record that has been dominated by secondary accounts, journalistic reconstructions, and palace-adjacent narratives for nearly thirty years.
The book's release on 22 September will be closely read against that existing record. Whether it confirms, complicates, or contradicts established accounts of the events of August and September 1997 is the question that matters most to historians, biographers, and anyone tracking the Diana story's long afterlife in British public memory.
