Prince William and Kate will take part in Canada Day celebrations Friday as the royal newlyweds continue a nine-day jaunt through Canada on their first official overseas trip.
The country's birthday celebration will include a concert and a speech by the prince. The couple also will hand out flags to newly minted Canadians at a citizenship ceremony earlier in the day.
Friday also would have been the 50th birthday of William's mother, Princess Diana, who died in a 1997 Paris car crash. In London, her admirers gathered to leave gifts outside Kensington Palace, which was her official residence.
The Duke and Duchess of Cambridge, as William and Kate are formally known, arrived Thursday to cheering crowds of thousands. Poised and confident, they thrilled crowds with warm, unscripted gestures, wading into throngs of well-wishers to shake hands and accept flowers and other gifts.
To cheers of delight, William addressed his hosts in both English and French, then cracked a joke about his language skills. "It will improve as we go on," the prince quipped, then noted how much he and Kate were "truly looking forward to this adventure."
