Written by Sarah Phelps (Dublin Murders), the series will see Foy star as Margaret Campbell, the Duchess of Argyll, with Bettany starring as her husband Ian Campbell, 11th Duke of Argyll, and Davis as Maureen, Marchioness of Dufferin and Ava.

A Very British Scandal will explore one of the most extraordinary and notoriously brutal legal cases of the 20th century: the divorce of the Duke and Duchess of Argyll.

Famed for her beauty, style and charisma, Margaret, Duchess of Arygll dominated the front pages when news of the divorce exposed accusations of forgery, theft, violence, drug-taking, bribery, and an explicit Polaroid picture that would haunt her for the rest of her life.

Investigating how the scandal reflected the social and political climate of post-war Britain, A Very British Scandal will look at attitudes towards women to ask whether institutional misogyny was widespread at the time. As the press, the judiciary and her contemporaries sought to vilify her, Margaret refused to go quietly, holding her head high with bravery and resilience as she was betrayed by her friends and publicly shamed by a society that revelled in her fall from grace.

Joining the stellar cast will be Amanda Drew (The Trial of Christine Keeler), Richard McCabe (Poldark), Phoebe Nicholls (The Elephant Man), Camilla Rutherford (Phantom Thread), Timothy Renouf (Afterlife Of The Party), Sophia Myles (A Discovery Of Witches), Sophie Ward (The Moonstone), Tim Steed (The Death of Stalin), and Katherine Manners (Press).

Also starring in the series will be Richard Goulding (The Crown), Jonathan Aris (Sherlock), Oliver Chris (Trying), Nicholas Rowe (Roadkill) and Miles Jupp (The Durrells).

A Very British Scandal is coming soon to BBC One and BBC iPlayer.
