Brian Hanrahan and Sally Taylor describe this afternoon's events in Portsmouth where, after 45 years' service, the royal yacht Britannia was decommissioned.
The Queen visited the ship and her crew for the last time and, with other members of the royal family, joined in a religious service on the dockside and watched Beating Retreat by the band of HM Royal Marines, who have accompanied the yacht on her travels around the world.
