Kings Charles III has surprised a crowd of people assembled outside Buckingham Palace awaiting his coronation. The king, Prince William and his wife, Kate, stopped Friday for a walkabout to shake hands and speak with an adoring throng of fans. Many of those in the crowd plan to spend the night hoping for a prime perch for the procession on Saturday and a view of the newly minted monarch waving from the balcony after the ceremony. Charles made the stop after a luncheon that followed a final rehearsal at Westminster Abbey. Camilla, the queen consort, did not take part in the walkabout.
