“Neither Sir John nor Dame Norma have discussed the Monarchy remotely in the terms you suggest in your email,” the spokesman said, adding: “What you report as depicted in the script has never been their view, never would be their view, and never will be their view.”

The latest season of “The Crown” is on track to air on Netflix on November 9, with Imelda Staunton set to take over the role of the Queen from Olivia Colman, who portrayed her in seasons 3 and 4.

According to Netflix’s description, season 5 centers around the Queen “approaching the 40th anniversary of her accession.”

Netflix responded to the furore on Monday, with a spokesperson saying in a statement: “The Crown has always been presented as a drama based on historical events.”

“Series 5 is a fictional dramatisation, imagining what could have happened behind closed doors during a significant decade for the royal family – one that has already been scrutinised and well-documented by journalists, biographers and historians,” the spokesperson added.

The show, which was created by Peter Morgan, swept the drama categories at last year’s Emmy awards, winning the top prize of the night, the award for outstanding drama series.
