Prince Harry's thawing relationship with Royals 'put back a peg over new documentary'

A new documentary, titled Harry - The Lost Prince, risks threatening the progress Prince Harry has made at mending his broken relationship with the Royal Family

Prince Harry's thawing relationship with the Royal Family risks going 'back a peg' amid the release of a new documentary, a royal expert tells The Mirror.

The Duke and Duchess of Sussex are the focus of a new film, titled Harry - The Lost Prince, which is scheduled to air on Germany's ZDF network tonight. The documentary, produced by award-winning filmmaker Ulrike Grunewald, promises to reveal fresh revelations about the couple's lives in the US after they quit their royal responsibilities in 2020.

Four years ago, Harry and his wife Meghan Markle relocated to California with the Duke telling Oprah Winfrey in a bombshell interview that he and Prince William were on 'different paths'. Harry then shared potentially damaging stories about his older brother and father, King Charles, in his memoir Spare, further dividing the royals.

But in recent times, there have been signs of their frosty relationship thawing, royal commentator Duncan Larcombe told The Mirror - and this new film has the potential to further divide them. Mr Larcombe said: "It's hard to say if the documentary will impact Harry's relationship with the royals because there are signs that things might be thawing.

"It's been quite a long time now since Harry and Meghan have dropped any bombshells. Since Harry's book Spare came out in January, it's been a relatively quiet time and he's kept his mouth shut. Since then, he's met up with his dad - albeit very briefly. It would be a real shame if the documentary put those possibilities of a thawing in the relationship back a peg or two."

Mr Larcombe went on: "I think any documentary that continues the criticism of Harry and Meghan's modus operandi is going to be damaging. It's in Germany so it's probably not going to make a big storm over in the US. But it's still a major blow for a couple who have seen their popularity plummet like a stone falling in a well since they left the UK."

The documentary comes as Meghan and Harry's professional distance has increased since they embarked on a joint tour of Colombia in the summer. Sources close to the couple say it shows their new "twin-track approach" with Harry focusing on his charity endeavours and Meghan on her entrepreneurial projects and business.

It is a marked difference from just two years ago when Meghan once likened herself and her husband to salt and pepper as they always "move together". Now, Meghan is gearing up to launch her brand American Rivieria Orchard next year, while Harry's Invictus Games will take place in February in Vancouver and Whistler in Canada.

Their solo public appearances are set to continue this week. Meghan is expected to appear at a glitzy Hollywood party honouring her celeb pal Tyler Perry tomorrow (December 4), meanwhile, thousands of miles away in New York, Harry will be at The New York Times DealBook Conference.
