William, 31, who served as a RAF search and rescue helicopter pilot until September, was watched by wife Kate as he laid a wreath of poppies at a memorial in central London. He followed his brother, army captain Harry, 29, who donned his ceremonial Household Cavalry great coat with wide red collar, in paying tribute on behalf of his father, Prince Charles (who is in India with wife Camilla, Duchess of Cornwall).
As in previous years, Kate, 31, watched from a balcony above Whitehall, central London, alongside William s aunt Sophie, Countess of Wessex, and Tim Laurence, the husband of Princess Anne. Kate donned a brooch in the shape of a poppy – the traditional symbol worn to honor those who have perished in wars.
Sunday’s ceremony (a continuation from Poppy Day in London on Thursday) remembered those who died in the two world wars and conflicts since.
A day prior, William stood in silence with 66,000 rugby fans as they paused for two minutes to remember those lost before a match between Wales and South Africa.
Following the game, William received some gifts for son Prince George – a little shirt from the Wales squad and a little springbok toy from the victorious South Africans.
