A former head of the Royal Navy has said that Britain is at risk from terrorists and traffickers because there are not enough boats patrolling UK waters.
Lord West told the Daily Mail that the situation was a "complete mess", as just three Border Force vessels patrol 7,700 miles of coastline.
Lord West said: "Already we have seen these illegal immigrants and I don't believe there aren't clever traffickers using the smaller ports to send them and I'm sure terrorists are aware of the route too.
"We need to get a grip on this. We are taking a gamble that nothing will ever happen in our seas and that is a risky view to take given the dangerous world we are in."
John Vine, who was independent chief inspector of borders and immigration until two years ago, said that despite warnings about the threat, there were not "sufficient resources" being given over to the issue.
Speaking to BBC Radio 4, he said: "I think it is reasonable to assume that this is something that might have been happening and if this is now the start of a new trend we certainly need to gather the intelligence and the resources to nip it in the bud."
He added: "We have seen the tragedies that have occurred in the Mediterranean.
"I am not a nautical person but I would have thought crossing the Channel - with all the hazards in terms of cross-Channel traffic as well as the weather and the sea conditions - are going to mean there is an equal chance of people losing their lives unless this is stopped."
