The brother of the late Princess Diana has claimed that Netflix drama The Crown is riddled with inaccurate and misleading information.

Earl Spencer says he turned down a request from the show's producers to film at his family's Althorp estate in Northamptonshire in England because of his unhappiness with the drama.

Speaking on Love Your Weekend with Alan Titchmarsh on ITV, he said, "There is a bit [of unease]. Actually, The Crown asked if they could film at Althorp and I said obviously not.

"The worry for me is that people see a show like that and they forget that it is fiction. They assume, especially foreigners. I find Americans tell me they have watched The Crown as if they have taken a history lesson. Well, they haven’t."

When Spencer was asked if he thought the show was accurate, he replied, "It is very hard, there is a lot of conjecture and a lot of invention, isn’t there? You can hang it on fact but the bits in between are not fact."

He added that he still feels a "duty" to his Diana, who died in a Paris car crash in 1997, and is always keen to protect her legacy.

"I feel it is my duty to stand up for her when I can. She left me for instance as guardian of her sons etc, so I feel there was a trust passed on," he said.

"And we grew up together, you know if you grow up with somebody, they are still that person, it doesn't matter what happens to them later. So yeah, I feel very passionately that I have a role to protect her memory."

His remarks follow reports that the British Royal Family is also unhappy with the show, which recently began its fourth season on Netflix.
