This is Tuesday 9th November 1943 outside the Mansion House in the City of London. The Prime Minister Winston Churchill is there to attend the annual Lord Mayor's Luncheon, he is with his daughter Mary Soames née Churchill. I can't be sure whether this photograph was taken before or after the Lunch, but on balance it's probably after Lunch.  Mr Churchill was famous for the amounts of alcohol he could put away. A City of London mounted officer can be seen in the background.
Once again the Geotag software has failed to show the correct location for this photograph, this is in the City of London, not Southwark!
