Their anger is understandable. Would so many Afghans be arriving in Sweden if Tony Blair had lived up to his promise of building a better government in Afghanistan? Would migrants be flooding through Libya if Britain hadn’t helped depose its government and usher in chaos? This is why Cameron can expect far more pressure to take extra refugees from Europe, especially if Britain votes to stay in the EU and loses its leverage. He should stand firm. We may be a country with a jobs boom and a strong record of social cohesion, but we’re a country where some 8,000 families are already needed to look after vulnerable children. How many more Britons can we realistically expect to care for unaccompanied refugees?
