In season 6, Sir Oswald Mosley (Sam Claflin) and his mistress Lady Diana Mitford (Amber Anderson) are two of the three main antagonists, along with American gangster Jack Nelson (James Frecheville). Mosley is introduced in season 5. Through him, both the audience and Tommy Shelby (Cillian Murphy) meet Diana. A member of the British aristocracy, she has similar political and social beliefs as her lover. She even claims to have a personal relationship with Adolf Hitler. If you are wondering who Lady Diana Mitford is in the show and whether she is based on a real person, we got you covered. SPOILERS AHEAD.
Who Is Lady Diana Mitford?
Diana makes her first appearance in ‘Peaky Blinders‘ season 6 episode 2, titled ‘Black Shirt.’ She accompanies Mosley to the venue where he is set to give a speech. It’s the same venue where she later meets Tommy and Lizzie (Natasha O’Keeffe). ‘Peaky Blinders’ quickly establishes Diana as Mosley’s equal partner in ambition and fascist beliefs. She is in the process of divorcing her first husband, Bryan Guinness of the Guinness family, and doesn’t seem to have a particularly high opinion of the man. Diana is vicious and evidently very intelligent.
In episode 3, titled ‘Gold,’ while Tommy desperately searches for a miracle cure for his ailing daughter, Ada takes charge of both light and dark aspects of his business. She meets with Diana and Mosley and invites them to Tommy’s home for a meeting along with Nelson. Diana makes her views on the Jewish and Romani people quite clear. Ada, smart and candid as always, doesn’t hide her revulsion for these people.
Diana develops an interest in Tommy, and they later sleep together. Diana later tells Lizzie about this, prompting the dissolution of Lizzie and Tommy’s marriage. It appears that Mosley was aware of it and likely encouraged it, believing that Tommy needs a better partner.
