(9:15 a.m. EST) -- Her Majesty The Queen will name the new P&O Cruises ship Britannia -- as predicted by Cruise Critic members.
The Queen -- accompanied by the Duke of Edinburgh -- will name the line's newest and biggest vessel on Tuesday, March 10, in Southampton.
It is the second time she has named a P&O Cruises' ship -- she named Oriana almost 20 years ago.
Cruise Critic members first noticed in January that the Queen had a March 10 engagement in Hampshire, and guessed she might be the ship's Godmother.
Carnival UK chairman David Dingle said:“We are honoured and proud that Her Majesty will name Britannia almost 20 years after she named the P&O Cruises ship Oriana.
“Britannia, a ship for the nation, will be the embodiment of contemporary Britain, and with her Union Jack livery she will fly the flag for Britain across the Globe.”
Britannia is the biggest ship in the P&O Cruises fleet, coming in at 141,000 tons and carrying 3,647 passengers, some 25,000-tons larger than P&O's previous biggest ship, Azura. It will also be the biggest ship ever built specifically for the UK market.
P&O Cruises officially took ownership of Britannia in a ceremony in Italy on Sunday.
To find out more about the ship, join marketing director Christopher Edgington for a live chat on Wednesday March 4.
