A self-confessed comedy hero to Ruth Jones, Hattie Jacques was a core part of postwar British comedy history. Roles in the Carry On films and TV sitcoms such as Sykes and Hancock cemented her place in the nation’s heart. Yet her off-screen life was just as extraordinary – married to Dad’s Army star John Le Mesurier, she began an unconventional affair with her driver, a scandal that could have ended her career. Ruth looks back at Hattie, a one-off drama that captures the astonishing story.
