A discarded life vest on the beach in Hardelot, FranceFour migrants have died while trying to reach the UK after one of the busiest days for Channel crossings this year. Three people were found dead on a boat off the coast of Dunkirk on Thursday, the French coastguard said, and a fourth is thought to have drowned in a separate incident near Boulogne-sur-Mer. The deaths come a day after Prime Minister Andy Burnham said the Government’s plan to curb Channel crossings was “working”, although he admitted there was “more to do”. “Every death in the Channel is a tragedy and a stark reminder of the dangers posed by criminal gangs exploiting vulnerable people for profit. “We will continue working relentlessly with the French and our partners overseas to prevent these perilous journeys.
