Prince Philip returned to the media spotlight on Saturday for the first time since being sidelined with a bladder infection earlier this month.
The husband of Queen Elizabeth II attended the annual Trooping the Colour ceremony in honor of the Queen's 86th birthday. Her actual birthday is on April 21, but the display of military pomp takes place later in hopes of better weather.
TV coverage on Saturday showed Prince Philip and the Queen riding in a carriage to the military pageant that involved horse guards and more than 1,600 officers and soldiers.
Prince Philip, 91, had to go to hospital with the bladder infection just before a star-studded diamond jubilee concert on June 4, but was released last week.
He missed three days of engagements earlier this week as he continued to convalesce, which included a Jubilee garden party at Sandringham, Norfolk, and the Queen's visit to Nottingham.
His first official return to royal duties -- without TV cameras -- came Friday for a dinner at Buckingham Palace, but he only returned to a public role on Saturday when he was shown on TV next to the Queen.
