More sniffer dogs and fencing are to be sent to Calais and Ministry of Defence land is to be used as a lorry park to ease related road congestion in Dover.
Cameron announced the measures after an emergency Cobra meeting of ministers. The prime minister, attempting to demonstrate that he is getting a grip on the crisis on his return from his tour of south-east Asia, admitted that the situation in Calais was “unacceptable”.
He stressed that the British government was working “hand in glove” with the French government to try to find a solution and he would be speaking to the French President, Francois Hollande, later on Friday.
“This is going to be a difficult issue right across the summer,” said Cameron. “I will have a team of senior ministers who will be working to deal with it, and we rule nothing out in taking action to deal with this very serious problem.
The Calais migrant crisis is likely to last throughout the summer, David Cameron warned on Friday as he announced additional security measures to protect the Eurotunnel railhead in France.
