The Queen has marked the centenary of the burial of the Unknown Warrior during a small private ceremony at Westminster Abbey, ahead of Remembrance Sunday. Her majesty laid a bouquet of flowers based on her own wedding bouquet, reflecting the custom of royal bridal bouquets being placed on the grave, which has been a tradition since 1923.
