The King and Queen arrived in elegance at Windsor Castle for the Order of the Garter service. The Order of the Garter is the most senior order of knighthood in the British honours system, where knights are chosen because of their commitment to public service. Some famous Garder knights include former prime minister Sir Tony Blair and Lord Lloyd-Webber. Princess Kate was back in attendance at the service, after having missed it last year due to her cancer treatment. Follow us for more royal news,
