A piece of scrub land in Calais has been nicknamed the jungle. It’s where “clandestines” lie in wait to sneak on to trucks heading for Britain. We film in the jungle to find out why, after travelling thousands of miles, the immigrants want to go the extra mile to get into Britain and not just stay in Europe. We film with the teams whose job it is to search trucks to stop this illegal human traffic. Also, an enforcement team in Stoke find illegal workers at a car wash firm who claim they’re 15 years old. One of the car washers we discover was recently removed from Britain to Iran after taking part in a Home Office scheme called Assisted Voluntary Repatriation. He pocketed £500 cash and a free flight. He came straight back to Britain through Calais on the back of a truck.
