The Princess Royal will review the seven ships in P&O Cruises' fleet today to mark the company's 175th anniversary. Thousands of people will line the waterfront at Southampton as the ships take the royal salute before departing on cruises.

The seven ships - Adonia, Arcadia, Aurora, Azura, Oceana, Oriana and Ventura - will sail into Southampton at dawn - the first time they have gathered together in their home port.

On Azura, ballerina Darcey Bussell, who named the ship in 2010, will be presented with seven captain's hats as jets from the Red Arrows perform a flypast overhead.

Later, Anne will be greeted by the seven ship's captains in a special ceremony on Oriana. The Princess, who named Aurora and Oceana, will be on board the Trinity House vessel Patricia to review the fleet. A total of 15,000 passengers will disembark and 15,000 new passengers will board the ships during the day, with the whole event bringing an estimated £17 million to the local Southampton economy.
