The Princess Royal reviewed the seven ships in P&O Cruises' fleet at Southampton in an anniversary marred by foul weather and traffic chaos.
These were the scenes this morning as, through the mist, seven liners - Adonia, Arcadia, Oceana, Azura, Ventura, Aurora and Oriana - arrived in Southampton. Mike Pearse has this report:
It's been a day of celebrations - a record seven luxury cruise liners and 40,000 passengers and crew, all in honour of P&O's 175th anniversary.
But, with the crowds came what some described as "organised chaos" - traffic jams in and around the city of Southampton - and passengers waiting hours for taxis or coaches to reach their destinations. Kerry Swain reports.
Passengers have complained that the 175th anniversary of P&O ferries has turned into "absolute chaos" as they try to disembark at Southampton.
The seven cruise ships are proving popular...as thousands flock to Southampton to take part in the P&O celebrations there are queues of over a mile to get into Ageas bowl.
The Ballet star Darcey Bussell has joined the captains of the seven luxury liners in their home port today, to celebrate the 175th anniversary of P&O. More pictures to follow.
P&O passengers at Ageas Bowl say it is organised chaos. There are long queues for coaches and taxis.
A flypast by the Red Arrows later this morning as part of today's 175 event has just been cancelled due to bad weather. The Red Arrows say the cloud is too low and safety has to be the top priority. A half hour display is still scheduled for 7:15pm tonight over the Solent.
