Actress Helena Bonham Carter, who is playing Princess Margaret in series four of The Crown, is well known in Oxfordshire.

For about six years she and her partner, film director Tim Burton, lived in Sutton Courtenay near Abingdon.

The home once belonged to Ms Bonham Carter's great grandfather Herbert Henry Asquith - the prime minister who took Britain into the First World War.

It is believed that Asquith entertained Winston Churchill on the property's lawn.

The couple split in 2014 but it is understood they remain friends and both still spend time at the country home with their children.

Mill House off Appleford Road has recently become the centre of a dispute between Mr Burton and his neighbours.

For generations residents of Sutton Courtenay have enjoyed unrestricted access to the river Thames via the islands that join the weirs.

Ms Bonham Carter said The Crown has a “moral responsibility” to make it clear to viewers it is a drama and not historical fact.

The regal drama has attracted criticism for its use of creative licence.

Oliver Dowden, the Culture Secretary, is expected to write to the US streaming giant this week, raising concerns that some younger viewers may mistake The Crown as a work of fact.

In an interview recorded for The Crown’s official podcast after filming on season four finished earlier this year, Ms Bonham Carter discussed the differences between “our version” and the “real version”.

She said: “I do feel very strongly because I think we have a moral responsibility to say, ‘Hang on guys, this is not… it’s not drama doc, we’re making a drama’.

“So they are two different entities.”

Earl Spencer, the brother of Diana, Princess of Wales, has called for Netflix to add a disclaimer making it clear The Crown is a work of fiction.

He told ITV’s Lorraine: “I think it would help The Crown an enormous amount if, at the beginning of each episode, it stated that, ‘This isn’t true but it is based around some real events’.

“I worry people do think that this is gospel and that’s unfair.”

Peter Morgan, who created The Crown, had previously appeared on the podcast to defend his right to creative licence.

Season four of The Crown explores the Prince of Wales’s relationship with Princess Diana.

Actress Emma Corrin has won plaudits for her portrayal of the princess.
