The BBC has commissioned a documentary on Princess Margaret, the younger sister of British monarch Queen Elizabeth II, the British media reported on Sunday.

The two-part documentary will be a “deeply personal account” that will examine a royal figure “whose life and loves reflected the social and sexual revolution that transformed Britain’s during the 20th century”, BBC was quoted as saying.

The Telegraph also quoted Basil Charles, former owner of a bar on the Caribbean island Mustique where the princess had a holiday home, as saying, “She was a trailblazer, she was a little bit of a rebel. She wanted to have the [royal] life but she also wanted to have a normal life.”

Margaret, who died in 2002, was a controversial royal – she was involved with a married Royal Air Force officer, Peter Townsend, in her youth, and later wed a commoner, Antony Armstrong-Jones, in 1960. There has been a revival of interest in Margaret after the Netflix series The Crown, in which her romance with Townsend and her strained relations with her elder sister have been explored. Margaret was portrayed by Vanessa Kirby in the first two seasons of The Crown, and will be played by Helena Bonham Carter in the third season that will be aired in 2019.
