This thrilling documentary focuses on three key themes in the private life of Diana, Princess of Wales. Diana didn’t want a divorce and her adultery seemed less calculated than that of her husband, Prince Charles, who was betraying his wife virtually from his engagement onwards – so did the British establishment make a serious error of judgement in its treatment of her? Secondly, was Diana planning to use her popularity to undermine Charles’s right to the throne and his desire to make Camilla his queen? And finally, was Diana ever likely to find true happiness in the wake of such public acrimony and personal heartache?
