Crowds line the street as Britain's Queen Elizabeth II rides in the Gold State coach from Buckingham Palace to St Paul's Cathedral for a service of Thanksgiving to celebrate to her Golden Jubilee. * The coach was built for King George III in 1762, and has only been used by the Queen twice before - for her Coronation, and her Silver Jubilee. Later, after lunch at Guildhall in the City of London, she will watch a parade and carnival along The Mall. Monday night saw more than one million people gather in central London to hear the Party in the Palace concert, and to watch a spectacular firework display.
