The show and the British royal family have a complicated relationship, with the real-life royals not always pleased with the way their story is being told on screen.
Last year, screenwriter Jemima Khan revealed that she chose to pull out of working on The Crown because of its "disrespectful" portrayal of the late Princess Diana's final years.
The 47-year-old screenwriter claimed she was asked to come on board to help creator Peter Morgan - with whom she briefly dated until February 2021 - with scripts covering the time before her friend died in a Paris car crash in 1997, but she ended up withdrawing from the project and asked for her contributions to be removed.
Khan had never spoken publicly about her friendship with Diana but was keen to help give an "accurate" version of events.
She said: "It was really important to me that the final years of my friend's life be portrayed accurately and with compassion, as has not always happened in the past".
