Harry, Meghan, William, Kate on Windsor walkabout
STORY: Relations have been strained between the two sons of Britain's new king after Harry and Meghan moved to the United States.
The four had not been seen so closely together since.
William's spokesman said he had invited Harry and Meghan, officially known as the Duke and Duchess of Sussex, to join him and Kate as they examined the flowers and spoke to crowds lining the entrance to Windsor Castle.
The sight of the two couples together will raise hopes that there has been a rapprochement following the death of Britain's longest-reigning monarch.
