In 1871 the first royal in living memory gave evidence in court - and led to his lover spending the rest of her life in an asylum.
Edward, known as Bertie, was the then Prince of Wales who later became King Edward VII, and stood in the dock to discuss his relationship with his close friend, Harriet Mordaunt.
She had claimed to her husband she had broken her wedding vows with the eldest son of Queen Victoria, as well as other men, leading to him filing for divorce.
