Tony Snowdon was one of the most flamboyant and charismatic figures of the 1960s, a talented photographer who charmed everyone around him. Princess Margaret was one of the most eligible women in the world. The Snowdons epitomized "The Swinging Sixties" - by far and away the most glamorous and modern members of the Royal Family. Their volatile marriage ended in scandal and divorce in 1978 - the first royal divorce for over four hundred years. At the time, Princess Margaret was blamed. Tony was seen as the wronged husband. Tony and Margaret: Inside a Royal Marriage tells a different story, drawing on extensive archive footage, unprecedented access to Lord Snowdon`s friends and family and exclusive material gathered by his biographer, Anne de Courcy.
