  The previous evening he and and Miss Markle, 36, had appeared at the same official event - the opening ceremony for the games - although they were careful not to be photographed together.
  In her absence, Harry, fifth in line to the throne, and dressed in jeans and his black Invictus polo shirt, watched one or two races on the track, handed out several medals and then made a point of meeting as many servicemen and women as possible in their preparation area.
  The Invictus Games are an inspirational Paralympic-style event for injured service personnel, created by the prince.
  Some 550 competitors from 17 nations are taking part in 12 adaptive sports such as tennis, golf and basketball.
