6.01 News: Flor McCarthy reports on the final ceremonies for the world biggest and most expensive cruise liner
Britain's Queen Elizabeth this afternoon officially named the Queen Mary 2, the world's biggest and most expensive cruise ship, in a lavish ceremony.
Tight security was in place in Southampton in England for the ceremony at Cunard's 150,000-tonne, £550 million liner in front of 2,000 specially invited guests.
The QM2 will sail on its maiden fare-paying passenger voyage to the US next week.
The launch of the 232ft-high liner has been overshadowed by a tragedy in the St Nazaire shipyard in western France where the ship was built by Alstom Chantiers de l'Atlantique.
Two months ago, a walkway being used by shipyard families on a tour of the liner collapsed and 15 people were killed.
