Prince William and Prince Harry's supporters react to new Diana book announcement

Both Prince William and Prince Harry's supporters are excited after the pair’s maternal uncle announced he will release a book about his late sister, Princess Diana.

According to Penguin Books, in "Swan Song: Diana, My Sister," Charles Spencer provides the most intimate, loving, and honest portrait yet of his sister.

The announcement came after Prince Harry and Meghan Markle stayed at Charles Spencer’s Althorp Estate during their latest visit to the United Kingdom.

The Duke and Duchess of Sussex also visited the grave of Princess Diana during their stay.

Royal fans and supporters of the US-based royal couple have expressed excitement while commenting on the announcement regarding the book’s release, expressing hope that Diana’s brother will reveal new details about his late sister.

"Swan Song: Diana, My Sister" is slated to be released next month in Britain and published around the world, telling the story about Diana, from his perspective, according to its publisher Michael Joseph, a division of Penguin Random House.

"With the 30th anniversary of Diana’s tragic death on the skyline, I’ve been inundated yet again with requests for interviews about my sister," Spencer said in a statement.

"This has convinced me to write down my own thoughts and memories, once and for ‌all, ⁠rather than having the discomfort of again reading the opinions of others, many of which are based on untruths that have become accepted over time."
