The RAF Red Arrows perform a flypast over Buckingham Palace, following the Trooping of the Colour parade, in London, Saturday June 15, 2013. Queen Elizabeth II celebrated her birthday with traditional pomp and circumstance _ but without her husband by her side. Prince Philip remains in the hospital, recovering from exploratory abdominal surgery. The queen invited her cousin, the Duke of Kent, to accompany her in a vintage carriage. Other royals — including Prince Harry and the Duchess of Cambridge — joined in the celebration Saturday. More than 1,000 soldiers, horses and musicians are taking part in the parade known as “Trooping the Color,” an annual ceremony. (AP Photo/ Chris Ison/PA )UNITED KINGDOM OUT
