Prince Harry and Meghan Markle braced for new documentary that warns of explosive revelations

An explosive new documentary about Prince Harry and Meghan Markle is set to spark fresh debate about the couple.

A controversial new film about the Duke and Duchess of Sussex, titled Harry - The Lost Prince, will air on Germany's ZDF network next month, The Express reports.

The documentary, which promises fresh revelations about Harry and Meghan, will debut at 8.15pm on December 3. It will explore Harry's struggles within the Royal Family and the broader impact of his personal quest for a meaningful role, following his exit from royal duties in 2020. According to ZDF, it will also address the death of the late Queen and the recent cancer diagnoses of King Charles and Princess Kate.

"The Royal Family has to deal with difficult developments and regroup after 'Megxit', the death of the Queen and Charles and Kate's cancer. What role will Harry play in the future?" a promo for the prime-time special states.

The description continues: "Even in his self-imposed exile in Montecito, California, he remains a figure of public interest. His commitment to charitable organisations - such as the Invictus Games he founded for wounded servicemen and women - always puts him in the spotlight."

The film will also touch on how the Duke has "always struggled with his role as a 'reserve'". The promo claims: "His disclosures in recent years have caused a lot of trouble within the family."

"Old versus young, traditional versus modern - the family conflict in the House of Windsor reflects the debate about the future of the British monarchy and its value for society," the network adds.

The makers of the doc, including award-winning filmmaker Ulrike Grunewald, travelled to New York to speak with sources close to the Sussexes and filmed in California, where Harry and Meghan live. The team behind the film also previously produced a special on Princess Kate and The Drama of the Windsors.

It comes amid news of Harry's own upcoming documentary series. It was announced on Wednesday that POLO, a five-episode docuseries produced by Harry and Meghan, will officially debut on December 10. The highly-anticipated show follows polo players "on and off the field" as they compete in the US Open Polo Championships.

Netflix shared the news and said: "Through fierce rivalries and intense training, viewers will get an unprecedented glimpse into the dedication and skill required to compete at the sport's highest level." It is well known that the Duke of Sussex has played polo for decades and is a huge fan of the equestrian sport.

"From a young player pushed to his limits by his demanding father, to a former golfer who's made significant sacrifices for the love of the sport, to the father-son duo widely regarded as the greatest players of all time — they all face intense personal and professional challenges as they vie for the coveted title," Netflix explained.
