People-smuggling networks in migrant camps are slick and organised. It took little more than a week for Hamid to find a people-smuggler in Calais. Within a couple of days, he was hiding near the beach with 75 others, waiting to cross the Channel in a small inflatable boat. Over 18,000 people so far this year have crossed the twenty miles of sea between Britain and France in small boats. Despite significant investment on both sides of the Channel, that's more than double the number last year. France's northern coastline is covered with dunes, foliage and hundreds of old WW2 bunkers where migrants can hide. High-security fencing and surveillance cameras now successfully protect the ports and Eurotunnel terminal, but surveillance is difficult among forested dunes. Hamid’s crossing cost £2,500, on top of the £7,275 he had paid to leave Afghanistan and cross Europe to France.
