BREAKING: Two more bodies have been found on board the stricken Costa Concordia cruise ship.
The bodies of two elderly passengers were found in a part of the submerged restaurant.
British passengers and crew, all of which survived the disaster, have started to arrive back in the UK.
BACKGROUND: The near-sinking of the Costa Concordia comes at a time when cruising has never been so popular. The UK's Passenger Shippinng Association reckons as many as 1.73 million cruise holidays will be taken by Britons this year.
Passengers arriving back in the UK have talked about how they thought their lives "were over" when the Costa Concordia began to sink.
Mr Radford went on to describe the moment the couple started to think something was wrong about the ship. He said they heard a "crunch" and then his drink started sliding across the table.
He said: "Then the lights went out and came back on. And then it (the ship) started going the other way, and quite a lot the other way."
Asked whether he'd consider going on a cruise again after the ordeal, he responded: "I'm not going on a cruise again."
UPDATE: Fifteen people are still missing from the Costa Concordia.
UPDATE: The bodies of two elderly men were found still wearing their life jackets, Italian authorities have said.
Italian coast guard commander Cosimo Nicastro said in a TV interview that rescue divers' safety was constantly being compromised by floating objects in the belly of the ship.
"There are tents, mattresses, other objects moving which can get tangled in the divers' equipment," Mr Nicastro said.
Owners of the Costa Concordia said "preliminary indications" suggested the captain may have been guilty of "significant human error".
Costa Cruises issued a statement calling into question Captain Francesco Schettino's judgment: "The route of the vessel appears to have been too close to the shore, and the captain's judgment in handling the emergency appears to have not followed standard Costa procedures."
The owners added: "We are aware that the lead prosecutor has levelled serious accusations against the ship's Captain, who joined Costa Crociere in 2002 as a Safety Officer and was appointed Captain in 2006, after acting as Staff Captain as well. As all Costa Masters, he has been constantly trained passing all tests."
Capt Schettino told Italian television he was not to blame for the ship, built in 2006, crashing into rocks. He said: "I don't know if it was detected or not, but on the nautical chart it was marked just as water and some 100-150 metres (328ft-492ft) from the rocks, and we were about 300 metres (984ft) from the shore, more or less. We shouldn't have had this contact."
Karen Jacques, chief operating officer, of Dryad Maritime, which provides risk forecasts and advice to mariners, said key questions investigators will want answers to included: what speed the cruiser was doing; why it took a different route; whether there was a problem below the water level that allowed the Concordia to list so quickly; what decisions Captain Francesco Schettino took and where he was before the collision; what his role was during the evacuation and when he left the vessel, and an inquiry into the evacuation itself.
Unconfirmed reports say a sixth body has been found by rescue teams scouring the ship.
The chief executive of Costa Crociere - the line that owns the Concordia - Pier Luigi Foschi will be talking to the media later today. He has scheduled a press conference for Italian reporters at 10.30am GMT and another for international media at 1pm GMT.
CONFIRMATION: Italian rescue officials say a passenger's body has been found in the wreckage of the Costa Concordia, raising to six the number of confirmed dead in the disaster. Sixteen people remain unaccounted-for.
Italian fire official Luca Cari told state radio that the victim was a man, found in a corridor in the part of the ship that was still above water. He said the victim was wearing the orange-colored life vest of passengers.
Before the latest death was confirmed, 15 people were said to be missing - but two more were added to the tally because two Sicilian women, originally listed among the evacuated, have not contacted relatives.
Mr Cari said a search of all the ship, including a divers' inspection of the submerged areas, continues, but the sea is becoming rough.
Meanwhile one of the British survivors, Rose Metcalf, has just been on BBC Breakfast TV recounting more of her ordeal.
Miss Metcalf, who as a crew member had a duty to help the passengers on board into lifeboats, said it was a "long process" getting them off the listing ship: "Because of the listing we knew they wouldn't be able to deploy all of the life rafts on the port side."
"We were literally throwing each other, we were creating human chains to try and pass people over gaps that if they dropped down there was no recovery from. As the ship was listing what was vertical was becoming horizontal."
Meanwhile, Carnival which owns Costa Cruises said the loss of the ship would wipe up to £62 million from its profits this year.
It said the grounded vessel would be out of service until at the least the end of its financial year to November 30, costing it between 85 million and 95 million US dollars this year. Carnivale said it was too early to calculate other costs.
