Prince Philip attends Trooping the Colour parade

The Duke of Edinburgh appeared in good spirits yesterday in his first major public engagement since leaving hospital, where he was treated for a bladder infection.

He joined thousands of well-wishers to celebrate the Queen's official birthday at the Trooping the Colour parade. The royal couple arrived in a glass coach for the military spectacle, rather than in Queen Victoria's 1842 ivory-mounted phaeton, due to the "unpredictable" weather. The Queen turned 86 on 21 April, but yesterday's ceremony marked her official birthday, always in June.
