An entire episode in series five will reportedly focus on Diana's bombshell Panorama interview in 1995. It comes after the Duke of Cambridge demanded it never to be broadcast again following an inquiry earlier this year which found Bashir used "deceitful behaviour" to secure his scoop.

       But sources say Netflix, which has a lucrative deal with Prince Harry and Meghan Markle said to be worth up to ￡112million, is going ahead with the episode.

       An insider told The Sun: “The Crown’s creators see the interview as the keystone moment in series five.

       "To the writers, the stormy marriage between Charles and Di led up to her outpouring on Panorama, and the aftermath of that decision defined her final months.

       “They are making a huge investment in that. The Crown has a track record of delving into areas of the Royal Family's history they’d rather be left alone.”

       Speaking earlier this year, William said: “This Panorama programme holds no legitimacy and should never be aired again.

       “It effectively established a false narrative which, for over a quarter of a century, has been commercialised by the BBC and others.”

       Royal commentator Margaret Holder said: “William was -dismayed at the time. It is also embarrassing for Harry.”
