Kate Middleton, Meghan Markle, Princess Beatrice and Princess Eugenie are among the royal brides to have placed their bouquets on the Tomb of the Unknown Warrior at Westminster Abbey after their weddings – but who started the tradition?

When Elizabeth Bowes-Lyon, who later became the Queen Mother, married Prince Albert (later King George VI) in 1923, she laid her bridal bouquet at the Tomb as tribute to her brother Fergus, who died at the Battle of Loos in 1915.
