Queen Elizabeth II was joined by her husband, Prince Philip, the newly-married Duke and Duchess of Cambridge and a host of other royals for the Garter Day ceremony.
Garter Day is a symbolic occasion when holders of the honour, chosen because they have held public office, contributed to national life or served the sovereign personally, meet to celebrate the most senior British order of chivalry.
The former Kate Middleton, also known as the Duchess of Cambridge, grinned broadly as she watched her husband, Prince William, take part in a procession ahead of the service - causing him to blush.
