The Crown creator has defended making up scenes in the latest series of the Netflix drama involving Prince Charles.

In the opening episode of the fourth season the Prince of Wales, played by Josh O'Connor, and his beloved great-uncle Lord Mountbatten are seen talking.

Charles Dance's Lord Mountbatten character warns Charles against pursuing Camilla Parker Bowles, who the Prince cheated on Princess Diana with.

In the episode the Lord is seen writing a letter warning Charles he is in danger of bringing "ruin and disappointment" to the family.

During the show the Prince only reads the note after the IRA assassinated Lord Mountbatten in August 1979.

There has been no evidence that the letter ever existed - but Peter Morgan, creator of The Crown, believes the interaction to be based in truth.

Speaking on the show's official podcast, he said: "What we know is that Mountbatten was really responsible for taking Charles to one side at precisely this point and saying, 'Look, you know, enough already with playing the field, it's time you got married and it's time you provided an heir'.

"As the heir I think there was some concern that he should settle down, marry the appropriate person and get on with it."

The show has received criticism in the past for showing fictional events.

Although the show employs researchers, Peter has defended his right to creative freedom.

Season four of The Crown explores Charles' relationship with Diana, Princess of Wales

He said: "In my own head I thought that would have even greater impact on Charles if it were to come post-mortem, as it were. I think everything that's in that letter that Mountbatten writes to Charles is what I really believe, based on everything I've read and people I've spoken to, that represents his view.

"We will never know if it was put into a letter, and we will never know if Charles got that letter before or after Mountbatten's death, but in this particular drama, this is how I decided to deal with it."

Season four of The Crown explores Charles' relationship with Diana, Princess of Wales.

Actress Emma Corrin has won plaudits for her portrayal of Diana.

Former royal butler Paul Burrell said the new season is a "fair and accurate dramatisation" of the royal family's treatment of Diana.

Season four of The Crown sees the Mountbatten-Windsor torn apart after the assassination of Prince Philip's Lord Mountbatten.

Talking about the powerful episode, Mountbatten's granddaughter India Hicks exclusively told us: "The Crown, I know the first two episodes, maybe the first three - focus on the murder of my grandfather, by the IRA."

She continued: "It's very strange when you have to share thoughts all this time later, then I was 11 when my grandfather was murdered."
