Princess Diana's Nieces Take Sides: Lady Kitty Spencer and Sisters Back Prince William as Feud With Prince Harry Deepens

Prince William and Prince Harry’s feud has deepened, with reports suggesting that even Princess Diana's nieces, including Lady Kitty Spencer, are now siding with their future king, the Prince of Wales.

Once regarded as inseparable, the regal brothers' relationship has fractured beyond repair, further exacerbated by Harry’s move to the U.S. and a series of explosive public statements and media projects that criticized the monarchy.

Now, the involvement of Diana’s nieces highlights a shift in family dynamics. Kitty Spencer and her sisters, the Ladies Amelia and Eliza, all daughters of , were recently seen supporting William, solidifying their alignment with the Prince of Wales in this ongoing feud.

The aristocrats attended the Centrepoint Awards on the evening of Wednesday, October 16, and turned on the glam with their stunning gowns.

Meanwhile, Harry’s absence from family gatherings, including the funeral of his uncle Lord Robert Fellowes in August, has fueled speculation about the Sussexes' complete detachment from both the royal family and the Spencer side​​. However, the Duke of Sussex does "seemingly" have the backing of Earl Spencer, Diana's brother, and his aunts, the Ladies Jane Fellowes and Sarah McCorquodale.

Amid security concerns, Harry has also distanced himself from family traditions and gatherings in the U.K., further complicating any potential reconciliation. Insiders believe that the feud could last for decades, casting doubt on whether the brothers will ever mend their relationship.

Meghan, Duchess of Sussex, is also said to play a part in the rift, if not being "the outright cause of it," in the words of one palace insider. The ex-actress has not set foot in Britain since Queen Elizabeth II's funeral in September 2022.

This new development in the feud follows "explosive" news of William's former private secretary Simon Case, who is set to step down as Britain's Head of the Civil Service to try his hand at writing... about the Duke and Duchess of Sussex.

There has been growing speculation that Case's book will include insights from when Harry and Meghan stepped back from royal duties. Although Case reportedly signed a non-disclosure agreement, it’s suggested that it only covers his work with the heir to the throne, leaving him free to discuss Harry and Meghan’s departure. Reports also reflect that the tome could become "quite lucrative" solely due to details the ex-secretary may spill about Team Sussex.
