The BBC has announced plans for a 'sumptuous' new documentary exploring the life and loves of Princess Margaret.
The show, whose title has not yet been announced, will look at how the Queen's late sister reflected the 'social and sexual revolution' that rocked Britain throughout the twentieth century.
The 'revealing' two-part series looks at how Margaret, who died in 2002 aged 71, 'redefined our image of the modern princess,' the broadcaster said.
It will feature an interview with Lady Anne Glenconner, a childhood friend who became lady-in-waiting and has previously spoken candidly about Margaret's affair with landscape gardener Roddy Llewellyn.
Described as a 'deeply personal account', the new BBC series will examine how Margaret combined the 'rebellious force of modernity and a deep respect for tradition'.
Hit Netflix drama The Crown has sparked a renewed public interest in the party-loving princess, portrayed by Vanessa Kirby with Helena Bonham-Carter set to take on the role in the next series.
The mother-of-two was a working royal with links to more than 80 organisations but her personal life was embroiled in scandal, with persistent rumours of affairs and reports of hedonistic holidays on the Caribbean island of Mustique.
Known as the Countess of Snowdon following her marriage to photographer Antony Armstrong-Jones in 1960, her high-profile divorce 18 years later made headlines around the world.
Before meeting Armstrong-Jones, she was engaged to RAF officer and divorcee Captain Peter Townsend, but called off their wedding in 1955 citing her 'duty to the Commonwealth'.
Twice her age and married with two children when the pair first met, their romance was plagued by controversy and Parliament refused to consent to the union.
Margaret's relationship with Earl Snowdon was similarly ill-fated, with the pair divorcing in 1978 after 18 years of marriage and a controversial 'loving friendship' with Llewellyn, with whom she was pictured holidaying on Mustique.
For the show, the BBC spoke to sources including close friend, royal aides, historians and biographers to reveal how Margaret 'embodied the spirit of cultural change'.
Producers spoke to Basil Charles, the owner of a bar on the Caribbean island of Mustique who met the Princess during her infamous holidays in the 1970s.
They also interviewed royal biographers Christopher Warwick, Anne de Courcy, and Craig Brown.
The show is expected to hit screens later this year.
