An upcoming TV series will reveal secret voice recordings made by Princess Diana in 1991 as she gives a never-before-heard insight into her life and experience in the royal family.

Diana: The Unheard Truth is scheduled to land on screens in August 2027, marking 30 years since she died in Paris in 1997.

All in, there are five hours worth of secret recordings, where Diana opened up about her former husband, King Charles, their marriage breakdown, and his ‘love for a woman called Camilla.’

Diana also reportedly spoke about her children, Princes William and Harry, Sarah ‘Fergie’ Ferguson, the disgraced Andrew Mountbatten-Windsor, her mental health and her battles with an eating disorder, bulimia nervosa.

The tapes were made by her friend Dr James Colthurst, who smuggled them out of Kensington Palace and delivered them to writer Andrew Morton.

They would later make up Morton’s bestselling 1992 biography about the princess, titled Diana: Her True Story. At the time, the book provided new insights into the life and times of Diana, and was deeply personal, candid and at times, shocking.

Currently, not even an hour of Diana’s recordings have seen the light of day — the new docuseries is set to change this.

It is being produced by Love Monday TV, which partnered with Morton and Colthurst (who also appear in the show to discuss the risks the trio took for the biography’s publication) to secure access to the tapes.

They are said to not only show Diana’s ‘infectious humour and twinkling laughter,’ but also spotlight her as a ‘resilient, perceptive, and relatable young woman.’

The show hints the recordings tell the story of a woman ‘finding herself in the brightest of global spotlights and navigating the challenges with grace, self-awareness, and determination.’

But, ‘most importantly,’ The Times reports that viewers will hear Diana’s ‘dreams for a future that could have been; a new chapter in which Charles goes off into the sunset with Camilla, leaving her free to carve her own path.’

The recordings also give the world a ‘rare opportunity to hear Diana’s perspective’ — many know that she had a complex, love-hate relationship with the press throughout her life.

While Diana frequently expressed frustration with the paparazzi and the constant scrutiny under the spotlight, she was able to leverage it to gain public support and highlight humanitarian causes.

Ultimately, the show says it will provide an opportunity for people to ‘recognise her legacy as one of agency, courage, and love.’

The producers added: ‘The raw words of Diana present a fuller portrait: a woman navigating pressure, redefining her role, and moving forward with conviction. It invites the public to encounter Diana not only through what happened to her, but through how she chose to respond.’

The news of these recordings comes shortly after Diana’s youngest son, Prince Harry, claimed that the royal life ‘killed’ his mother.

While making a keynote speech at the $1,000-a-head InterEdge Summit in Melbourne Park as part of his and Meghan’s recent tour of Australia, Harry said that he felt ‘lost, betrayed, or completely powerless’ in his youth.

He told the audience that he had his ‘head in the sand for years and years’ until he and Meghan stepped down from royal duties in 2020.

Harry suggested that his decision to leave the royal family was also something his mother would have wanted for him.

‘After my mum died just before my 13th birthday I was like “I don’t want this job. I don’t want this role. Wherever this is headed, I don’t like it”.

‘It killed my mum, and I was very much against it, and I stuck my head in the sand for years and years.

‘Eventually, I realised well, hang on, if there was somebody else in this position, how would they be making the most of this platform and this ability and the resources that come with it to make a difference in the world?

‘And also, what would my mum want me to do? And that really changed my own perspective.’
