While Britain has been convulsed by the European Union referendum vote and its consequences, the refugee crisis has carried on as usual. We just don’t hear so much about it.

Exodus: Our Journey To Europe (11-13 July) was an ambitious documentary series spread over three nights. As well as professional footage, it used material collected from the mobile-phone cameras of the refugees as they made their arduous journeys into and across Europe. It presented a picture of human misery, but also hope.

Among the refugees we met was Isra’a, an 11-year-old girl living in Turkey, having left Syria for the unimpeachable reason that her house was hit by a missile. Her father, Tarek, had been a restaurateur in Aleppo. Now, aided by Isra’a, he sold black market cigarettes in Izmir while he saved enough to cross the narrow strip of water into Greece.

On the streets of Izmir you can buy waterproof bags for your phone: the refugees use their phones to provide maps. Then there were the life jackets. “The majority of them make you sink instead of float,” explained one sceptical customer. Tarek arranged to take his party of eight adults and eight children to Greece in a rubber dinghy. It cost €12,000 (£10,200).
