In just two months the population of the notorious shantytown filled with migrants desperate to cross the Channel has doubled sparking a border alert. Experts last night said their increasingly dangerous attempts to get on board lorries and even tourist cars could put the safety of travellers at risk ahead of one of the busiest weekends of the year at the port.

The fears of chaos on the roads leading to the ferry port were heightened yesterday after a refugee was killed in a fresh outbreak of violence in the camp. The soaring population of the Jungle comes despite French authorities repeatedly promising to reduce its size to 1,500 inhabitants. Ukip leadership candidate Diane James said: “The Calais problem will not go away. France has to have the courage to arrest and deport.

“A hard-line, yes, but the only way to send a clear message. A country that can ban the burkini should be capable of dealing with this problem and not holding the UK to ransom in the process.” A census put the Jungle population at 4,480 in June but aid workers estimate it is home to at least 9,100 now with hundreds more arriving each week. On Monday night a 37-year-old Ethiopian migrant was killed and 15 others seriously injured during a “hugely violent” fight between rival UK-bound gangs from Sudan and Afghanistan.

The gangs were competing to get access to the motorway so they could try and force vehicles to slow down or stop, ambush them and smuggle themselves into the UK. A source close to the murder probe said: “As two gangs from Sudan and Afghanistan competed to get on to the motorway to stop the lorries a fight broke out. Weapons including knives and sharpened sticks were used and the situation got very violent. It was a hugely violent fight and there were similar disturbances in other parts of the road system.” The bloodshed follows a disturbingly familiar pattern as the migrants crisis turns ugly. Scores of British vehicles heading to the port have been pelted with missiles while migrants start fires on the carriageway and throw debris into the road.

The late August bank holiday traditionally marks the end of the summer holiday season. The long weekend will see a huge increase in the amount of traffic heading to the ferry terminal prompting a warning from experts. Road Haulage Association chief executive Richard Burnett said: “The number of migrants in Calais has now topped 9,000 with more arriving every day, all with the sole intent of reaching the UK by whatever means possible. “Only the French military have the number of personnel that are so desperately needed. We have been calling for this course of action for over 12 months yet attacks on hauliers, and now motorists are increasing. Does an HGV driver, or even a family, have to die before action is taken?”

The majority of migrants have come from Afghanistan, Sudan, Iraq, Iran and Somalia and want to make it to Britain to join friends and relatives who have already arrived illegally. Rioting frequently breaks as they fight over prime spots from to launch assaults on moving traffic and “ownership” of the dual carriageway that leads to the port. Charity L’Auberge des Migrants who carried out the latest head count warned the camp is already a “pressure cooker about to blow”. Ukip migration spokesman Steven Woolfe said: “A long term solution cannot be found if the number of migrants travelling to Calais and the surrounding area continues to increase year on year.

“As the UK begins its journey of leaving the EU it is critical the government continues to invest in additional security measures, strong borders and a well-resourced border force to reduce illegal migration.” The Daily Express has led the way in exposing how the migrant crisis on our doorstep has rapidly deteriorated. Last year 84,088 people were caught trying to sneak into the UK, the equivalent to 230 a day or one every six minutes.
