Prime Minister David Cameron has said Britain will send extra sniffer dogs and fencing to France in response to the Calais migrant crisis.
Mr Cameron also confirmed Ministry of Defence land will be used to ease congestion with freight vehicles queued in Kent to head to the continent.
"We're going to take action right across the board," Mr Cameron said, confirming he will speak with French President Hollande later today and extend an offer to work "hand in glove" with his administration.
"This is going to be an issue right across the summer," he added. "We rule nothing out to dealing with this very serious problem. We're absolutely on it. We know it needs more work."
A joint police operation has been launched to target people-smugglers who profit from the desperate migrants trying to reach the UK.
Calais' Mayor has accused Cameron of treating the region with "contempt" - and called on authorities to open the border unless help is given
