PRINCESS MARGARET: THE REBEL ROYAL How Margaret rocked the royals

She smoked, drank, loved a party and befriended celebrities – in many ways, the Queen’s younger sister (far right, with the Queen) reflected the social and sexual revolution that transformed Britain during the 20th Century. In a two-part, in-depth profile, archive footage, revealing interviews and anecdotes flesh out Margaret’s life as she redefined the public’s image of the modern princess. Among the contributors in the documentary are her childhood friend and lady-in-waiting, Lady Glenconner, and biographer Christopher Warwick. BritBox, from Thursday
