Wallis Simpson enjoys a cup of tea.

The secret photos of The Duke and Duchess of Windsor premieres on ITV Choice (123) on Saturday 14 May at 21:00.

In 1936, the then British King Edward VIII announced that he intended to marry Wallis Simpson, an American socialite who had been previously married twice before.

But the King's desire to wed a woman who had two living ex-husbands threatened to cause a constitutional crisis in the United Kingdom and, in the December of that year, he announced his abdication from the throne in order to marry "the woman I love". After the abdication, the former king was created Duke of Windsor by his brother and successor, King George VI. Edward married Wallis six months later, after which she was formally known as the Duchess of Windsor, without the style "Her Royal Highness". She was instead styled as "Her Grace", a style normally reserved only for non-royal dukes and duchesses.

Before, during, and after World War II, the Duke and Duchess of Windsor were suspected by many in government and society of being Nazi sympathisers. In the 1950s and 1960s, she and the Duke shuttled between Europe and the United States, living a life of leisure as society celebrities. After the Duke's death in 1972, the Duchess lived in seclusion, and was rarely seen in public. Her private life has been a source of much speculation, and she remains a controversial figure in British history.

Now, the intimate love story of Edward VIII and Wallis Simpson as it's never been seen before, is revealed in the one hour documentary The Secret Photos of the Duke and Duchess of Windsor which will be screened on British Entertainment channel ITV Choice on Saturday 14 May at 21:00. The one-hour documentary offers insight into the romance between the King and "the divorcee" revealing, for the first time ever, more than a thousand personal photos that the Duchess of Windsor gave to her gardener on the Duke's death and which have remained, until now, hidden in a trunk of mementoes.
