The Royal Family won’t like the Princess Diana movie “at all”, according to a royal expert.

Robert Jobson – whose new book is called ‘Prince Philip’s Century: The Extraordinary Life of the Duke of Edinburgh’ – thinks the royals are certain to dislike the upcoming drama film, which sees Kristen Stewart portray the late Princess.

He said: “They won’t like it, but they would have expected it. It is the truth.”

Robert got to know the Princess before she died in a car accident in Paris in August 1997.

He shared: “It’s going to be 25 years in 2022, since she died … I’m 56 now. I was kinda a young man covering the story at the time, but [I] knew her as a person.”

However, he thinks it’s “inevitable” that the royals won’t like ‘Spencer’.

He told Us Weekly: “The royals won’t like [the biopic] at all.”

Robert also observed that Kristen, 30, will be under a huge amount of pressure playing the iconic royal.

However, he conceded that the actress looked remarkably similar to the late Princess in a recent publicity photo.

He reflected: “I think the most important thing is how well the actress can interpret the role. We’ll have to wait and see on that.

“As for the photographs of her, I thought she looked remarkably like the photograph of [Diana]. Having been someone who has met Diana and knew her fairly well, I thought it was uncanny, really.

“But we’ll just have to see. I think what’s more important is the authenticity of the portrayal, and we’ll have to see how that develops because my understanding is it’s going to be a good script and it’s going to be a good premise, but it might not necessarily have actually happened in the way they’re saying.”
