There is no doubt that it is an extraordinary image. Just ten months before it was captured, the man at its centre was the King of Great Britain, Ireland and the British Dominions beyond the Seas, Defender of the Faith, and Emperor of India.
And yet here he is, the uncle of our present Queen, surrounded by beaming Nazi bigwigs, proudly giving a Heil Hitler salute, looking for all the world like some despicable Fascist puppet dictator.
The photograph emerged only this week when an auction house in Wales announced that it was up for sale, along with many similar photographs from the Duke of Windsor’s trip to Germany in October 1937.
Coincidentally, it comes in the wake of the publication of a jaw-dropping home movie showing our Queen, then a seven-year-old princess, giving a Nazi salute in 1933, abetted by the Duke, who was then the Prince of Wales.
