Princess Diana died haunted by an event she believed had hurt William and Harry

As the 30th anniversary of Princess Diana’s death approaches in August 2027, preparations are already taking shape among her sons and her global community of admirers.

William and Harry, 40, are expected to mark the milestone both privately and publicly, with her youngest son planning to make a tell-all documentary about his mother, which will include details of how her death and funeral affected him and her stormy marriage to Charles.

Sources said both brothers are aware of the emotional weight of the anniversary and its significance for charities Diana championed, particularly those focused on homelessness and mental health.

For Diana’s fans, the anniversary will be a moment of memory and renewed affection for a figure who continues to resonate for generations.

Informal memorial events are expected at Kensington Palace, Paris and other locations related to her life, alongside exhibitions, documentaries and charity initiatives inspired by her humanitarian work.

A palace source said: “Three decades later, Diana’s influence remains vibrant, with admirers and family alike preparing to reflect on her compassion, vulnerability and lasting impact.”
