The emergence of at least six rural settlements in the Nord-Pas-de-Calais region has raised fears of a fresh border crisis.
Officials thought the mayhem of the past two years had finally ended in October when the Jungle camp was bulldozed.

It’s a daily risk and I dare not stop near the port because it’s so dangerous
British trucker Graham Gammond, 65, from Hereford, said: “The problem is now moving further away from Calais.
“It’s a daily risk and I dare not stop near the port because it’s so dangerous. Service stations are the perfect place for people smugglers. The situation has become unreal.”

Around 100 are huddled in a muddy shantytown in woods close to the village of Norrent-Fontes, around 30 miles south east of Calais.
Although the camp has existed for a while numbers inside are swelling because refugees have started to leave reception centres where they were taken after the Jungle was razed.
They said they wanted to claim asylum and were being helped in their efforts to live rough by a British man.
The blaze of publicity surrounding the dismantling of the Jungle means refugees are making every effort to avoid detection.
Experts now fear camps like this will “mushroom” across the northern French countryside.
Their squalid settlement is a short walk to the Saint Hilaire Cottes services on the A26 motorway to Calais which has become a magnet for trafficking gangs.

A source close to the crisis said: “There are rumours of smaller camps mushrooming all the time but this is to be expected because migrants are still arriving and heading for Calais. However, the authorities there are playing the Three Monkeys game – see no evil, hear no evil and speak no evil.”
Tory MP Charlie Elphicke said: “Getting the Calais Jungle dismantled was a huge victory in the war against evil people traffickers.
“The number of people trying to break into Britain through Dover has plummeted and the people of Calais have got their town back.
“Yet the threat of illegal immigration remains. This is why we must be more vigilant than ever at the border.
“It’s clear that dangerous and violent criminal gangs are still actively working to traffick people. That’s why the French must keep up the police presence to stop new camps forming. “We must stop any new camps from forming before the first tent is pitched.”

The Home Office has failed to respond to a Freedom of Information request submitted by this newspaper demanding to know what the figure was last year, the latest available.
The Home Office said: “The UK and France worked extremely closely to coordinate the successful clearance of the main camp in Calais and ensure those in need of protection were moved to suitable facilities.
“The French Government is alive to the threat of new camps appearing in Northern France and both countries are clear that we must continue to fight together against the callous criminals that coordinate people smuggling.”
