The Royal family braved the wet weather on Saturday to celebrate the Queen's official birthday with the traditional Trooping the Colour parade.
Thousands of onlookers lined The Mall, in central London, to see the Queen and the Duke of Edinburgh ride past in a horse-drawn carriage from Buckingham Palace.
The parade is based on traditional preparations for battle, where the colours, or flags, were paraded in front of troops so they could recognise them.
The 1,100 soldiers taking part put on a colourful display of precise marching, horse riding and military music.
British Prime Minister Tony Blair, his wife Cherie (in the middle), and their daughter Kathryn were among the VIPs invited to watch the ceremony at the parade ground.
Although the Trooping the Colour marks the Queen's official birthday, on 16 June, her real birthday is on 21 April.
After the parade, Prince William and Princess Eugenie joined their grandmother on the balcony of Buckingham Palace to watch a Red Arrows fly-past.
By now it was pouring with rain, but hundreds of people stayed around to watch the colourful air display.
