What to do about illegal migration from Africa into Europe? The EU’s repatriation programme seems at first like a great idea. Rather than just watching as desperate people risk their lives in the Med, we persuade them to go back home and help them to remake their lives there. The EU Emergency Trust Fund for Africa has coughed up £125 million for the scheme and about 25,000 migrants have already taken part, most heading home to west and central Africa.
