It’s over two years since the authorities in France closed down the Jungle, the large migrant camp in Calais on the French coast. At its height more than 9,000 people from around the world lived in the camp while attempting to make it across to the UK, often hiding in the back of lorries or packed into small boats. It was hoped the camp's closure would stem the number of people risking their lives to try to get to Britain. But has it worked? In December, Britain’s Home Secretary, Sajid Javid, declared the number of migrants attempting to cross the English Channel in boats a 'major incident' and since then more than 100 people have been picked up in 2019. For Assignment, Paul Kenyon investigates the British gangs making big money and risking migrants' lives smuggling them across the Channel and reports on the attempts to break up their networks.
