Overview
- Earl Spencer announced the memoir publicly on Tuesday, saying he wrote it to set down his memories and to challenge “untruths that have become accepted over time.”
- Penguin Michael Joseph will publish Swan Song: Diana, My Sister on 22 September 2026 with translations into 12 languages and an international release planned.
- The publisher, Daniel Bunyard, described the book as containing “many revelations that will draw considerable attention” and praised Spencer’s intimate vantage point.
- Coverage says the memoir is expected to cover Diana’s childhood, her troubled 15-year marriage to the then‑Prince of Wales, and the week following her 1997 death in Paris, including behind‑the‑scenes funeral disputes referenced in prior accounts.
- The release is timed to feed renewed public interest ahead of the 30th anniversary and could shape how the public remembers Diana while drawing further media scrutiny of family and funeral arrangements.
