Britain's Prince Philip made his first official public appearance yesterday (16.06.12) since being hospitalised with a bladder infection.
The Duke of Edinburgh - who was released from hospital last weekend after receiving five days of treatment - attended the annual Trooping the Colour ceremony in London, alongside wife Queen Elizabeth and other royal family members.
The 91-year-old royal - who turned 91 last Sunday (10.06.12) - , waved and smiled to cheering crowds gathered outside Buckingham Palace as he watched a military fly-past from the balcony of the royal residence to mark the queen's official birthday.
Other members of the royal family who took to the balcony included Prince Charles and his wife the Duchess of Cornwall, the Duke and Duchess of Cambridge, Prince Harry, Prince Andrew, Prince Edward and Princess Anne.
Earlier in the day Philip rode with the queen in a glass coach to and from a nearby parade ground where they watched an hour-long tattoo performed by 1,600 soldiers and horse riders in traditional military uniforms.
Charles, William, Anne and the Duke of Kent all took part in the ceremony while the other members watched on.
