The Duchess of Cambridge made a surprise appearance with Prince William after he carried out a poignant job that used to be undertaken by his younger brother Prince Harry.
Today, William took part in a wreath-laying ceremony at the Cenotaph in Whitehall to commemorate Australians and New Zealanders on Anzac Day.
At the last minute, it was announced that wife Kate would then be joining him for a service of commemoration and thanksgiving at Westminster Abbey after the wreath-laying.
