I'm grateful to LDP reader Peter who was at today's Beating Retreat ceremony. It was in front of the Duke of Edinburgh, who has just turned 85. Peter sent me this photo, and I am pleased to present it to you. If you haven't heard the DofE stories before, enjoy this list of his gaffes. This was taken at Horseguards parade, where a few weeks a go the Sultans Elephant was trumpeting about.
