Panorama goes undercover to find the sweatshops making clothes for the British high street. Tens of thousands of Syrian refugees and children are working illegally in the Turkish garment industry. They are often paid very little, work in harsh conditions and have no rights. Reporter Darragh MacIntyre discovers refugees and their children working in the supply chains of some of the best-known brands.
