Netflix has refused to warn viewers of The Crown that the series is a work of fiction and may be historically inaccurate. Critics of the show, which dramatises the history and relationships of the Royal family since the 1950s, say that key scenes are invented and have urged the streaming giant to put a disclaimer at the start of each episode. Last week Oliver Dowden, the Culture Secretary, joined calls for Netflix to inform viewers that parts of its historical drama are made up and Helena Bonham-Carter, who plays Princess Margaret in the show, said Netflix had a "moral responsibility" to air the disclaimer. But the US company claimed on Sunday that it was widely understood that The Crown was a work of fiction. Netflix told The Mail on Sunday: "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." For weeks, The Crown has faced criticism from politicians, Royal experts and close friends of the family for its fictional portrayal of British history.
