The father of one of the missing yachtsmen made a direct plea to Prime Minister David Cameron to search for the four crew members of the lost Cheeki Rafiki.
"These are guys that are an inspiration to Britain, they are your Britain. We owe it to them. We look after our own people, we need to get out there and search for them," Graham Male, father of James Male, said.
The US Coastguard called off its search on Sunday morning for the crew of the Cheeki Rafiki yacht which was lost on Friday after it got into difficulties 620 miles (1,000km) east of Cape Cod in Massachusetts.
With no sign of a life raft or of debris, and with nearly 20,000 square miles having been searched, the hunt continues for another day.
Veteran yachtsman Tony Bullimore tells ITV News that there is a "strong possibility" the yachtsmen are still alive in the life raft.
