The controversial show, which is charting the life of Queen Elizabeth II, focused heavily on the relationship between Diana and Charles in its most recent season.
Charles Spencer, brother to the late Princess Diana, suggested each episode should begin with a health warning stating “this isn’t true, but it is based around some real events”.
There has been criticism of the show for depicting Charles continuing his relationship with Camilla Parker Bowles throughout his marriage to Diana, when in fact it was only rekindled towards the end.
Season Four also shows Lord Mountbatten writing Prince Charles an extremely personal letter just before his assassination by the IRA, when this never actually happened.

The couple will produce films, documentaries and children’s shows for the streaming giant.
After the deal was confirmed Ted Sarandos, chief content officer at Netflix, spoke about how delighted the company is with its new partnership.
He said: “Harry and Meghan have inspired millions of people all around the world with their authenticity, optimism and leadership.
“We’re incredibly proud they have chosen Netflix as their creative home – and are excited about telling stories with them that can help build resilience and increase understanding for audiences everywhere.”
No members of the Royal Family have spoken publicly about the series but senior royal sources have suggested it is causing significant disquiet.
Speaking to The Telegraph about Charles and Camilla a Palace source said: “The new series paints the Prince and Duchess in a very unflattering light but at least at the start of reality shows like The Only Way Is Essex they admit that some scenes have been invented for entertainment.
“This is trolling with a Hollywood budget. The public shouldn’t be fooled into thinking this is an accurate portrayal of what really happened.”
However according to one source, speaking to Vanity Fair, the Duchess of Cornwall has been appreciating the show.
