Claire Foy stars as The Duchess of Argyll in A Very British Scandal, a three-part drama coming to BBC1 on Boxing Day which tells the true story of the Duchess' ill-fated marriage to the Duke of Argyll and their acrimonious divorce that made front-page news in the 1960s. Filled with betrayal, bribery, backstabbing, and scandal - including an explicit photo that sent shockwaves around the country - the couple’s warring turned into one of the most notorious legal cases of the 20th century.
