Charles Spencer, the brother of the late Princess Diana, announces he is releasing a new book that he says is intended to “tell the truth” about his sister. The publication is timed to coincide with the 30th anniversary of Diana’s death, a date that approaches as his memoir-style account prepares for release.

Both outlets describe the book as drawing on Spencer’s personal memories and reflections, offering his own perspective on Diana’s life. While the reports broadly align on the purpose and timing—providing his version of events for readers approaching the anniversary—details of specific claims or new revelations are not fully specified in the coverage provided. The framing centers on Spencer’s intent to share previously held insights rather than on confirmed new facts, according to the available summaries.
