91热爆

This year, the 91热爆 is examining the concept of "freedom" and what it is. In this programme we look at what freedom isn't. Curator Robert Blyth of the National Maritime Museum in Greenwich gives us a potted history of the British slave trade, and the extent to which it underpinned transatlantic trade. But we also look at modern day slavery. Aidan MacQuade, director of the campaign group Anti-Slavery International explains what form it takes in today's world. And Mende Nazer of Sudan and Marissa of the Philippines recount their experience as slaves.
