The Queen and Duke of Edinburgh have paid tribute to World War One personnel at a Tower of London art installation featuring thousands of ceramic poppies. The Queen laid a wreath at the "Blood Swept Lands And Seas Of Red" exhibit, where each poppy commemorates a fallen WW1 serviceman. By 11 November - Armistice Day - there will be 888,246 ceramic poppies, one for each British and colonial death.

The Duke and Duchess of Cambridge and Prince Harry visited in August. Hundreds of spectators lined the perimeter of the tower's moat during the royal visit.

Stage designer Tom Piper, who helped create the poppy installation, said the Queen described the artwork as "impressive."
