Earl Spencer, brother of Princess Diana, has released his memoir “Swan Song: Diana, My Sister,” condemning the British royal family’s treatment of his sister. The book revisits the 1997 funeral where he publicly rebuked the House of Windsor, including King Charles, for stripping Diana of her royal title after her divorce. Spencer, now 62, alleges Charles sounded “giddily elated” after Diana’s death, suggesting relief at being free to marry Camilla Parker Bowles.

The memoir, released Sept. 22, 2026, draws on Spencer’s unique perspective as a member of the Spencer family, which has held Althorp for over 500 years. He details his career as a journalist, historian, and podcast host, and his history of abuse at Maidwell boarding school. Spencer, divorced three times, married for the fourth time earlier this year.

The book intensifies long-standing tensions between the Spencer and Windsor families, framing Diana’s legacy as independent of royal titles.
