Quick Summary

Charles Spencer, Princess Diana’s brother, suggests in his new book "Swan Song: Diana, My Sister" that Prince Harry is developing a documentary about their mother. The Daily Mail earlier reported that Harry had returned to the UK partly to work on this project and has been seeking input from those who knew Diana well. Royal expert Richard Kay claims the documentary will occupy much of Harry’s time over the next year and might create tension with his brother, Prince William.

Story summary

Prince Harry is reportedly considering making a documentary about his late mother, Princess Diana, ahead of the 30th anniversary of her death in August 2027. According to sources, Harry has approached several friends and relatives, including Diana's brother Charles Spencer, who declined similar offers to avoid being labeled as a "talking head" in flawed productions. The documentary would likely be produced by Archewell Productions, the media company founded by Harry and his wife Meghan Markle, under their multi-year first-look deal with Netflix. This project could potentially strain relations within the royal family, especially given previous tensions between Harry and William over media portrayals of Diana.
