Prince William and Prince Harry along with Kate, the Duchess of Cambridge and Meghan, the Duchess of Sussex, reunited in central London for "Remembrance Sunday" -- a memorial day observed in the British Commonwealth to honor fallen military members of service.
Queen Elizabeth II led events at the Cenotaph war memorial in Whitehall, London, for the annual laying of the wreaths. Two minutes' silence was observed throughout the U.K. at 11 a.m. -- the eleventh hour of the eleventh day of the eleventh month.

William, Harry, Kate and Meghan were at the Royal Albert Hall on Saturday night, marking the first time they have all appeared together in public since Harry and Meghan commented about their struggles with constantly being in the public spotlight.

But look, we’re brothers, we’ll always be brothers. We’re certainly on different paths at the moment. But I will always be there for him, as I know he’ll always be there for me."
The royal couples were attending a remembrance concert organized by the Royal British Legion, a charity for war veterans. There were musical performances by various divisions of the Armed Forces including the Royal Marines, and veterans shared memories of the war. British actors read war poetry and a series of video shorts were played during the event.
Prince Andrew, Prince Edward, Sophie, the Countess of Wessex and other nobility were also in attendance.
British Prime Minister Boris Johnson and his girlfriend Carrie Symonds were also in the royal box.
This year's ceremonies were particularly poignant as they marked the 75th anniversary of D-Day and the Battle of Normandy. D-Day is often considered the most pivotal battle of World War II, leading up to the defeat to the Nazis and the end of the war.
