Given the scandal surrounding Andrew Mountbatten-Windsor, we thought we'd examine an eerily familiar moment in British history. In January 1809 the Duke of York became the subject of a huge and embarrassing news story. It was a story of sex, power, money and corruption right at the heart of British politics. One of the stars of the affair was a woman of no rank, title or fortune. Her name was Mary Anne Clarke.
