Season four of 'The Crown' has proven its most popular season yet. But not everyone has been pleased with the historical drama.

As previously reported, the Royal Family are very unhappy with the series. Close friends of Prince Charles described 'The Crown' as "trolling with a Hollywood budget."

Insiders described the show as "cruel", "unfair" and "false."

A source at the palace said: "The public shouldn't be fooled into thinking this is an accurate portrayal of what really happened."

Royal biographer Sally Beddell Smith similarly called the show an "extreme and egregious misrepresentation."

She added that: "Viewers should not be fooled. This is a 'Downton Abbey' version of the Royal Family."

Complaints were particularly launched against the depiction of Prince Charles' and Diana Spencer's marriage. The characterisation of Camilla Parker Bowles was also criticsed.

Recently, the UK government got involved. Culture Secretary Oliver Dowden penned a letter to Netflix insisting the streamer add a disclaimer that 'The Crown' is a work of fiction.

The streaming giant has responded.

Speaking to THR, a Netflix spokesperson said: "We have always presented 'The Crown' as a drama - and we have every confidence our members understand it's a work of fiction that's broadly based on historical events.

"As a result we have no plans - and see no need - to add a disclaimer."
