HARDtalk

Across the world sixty five million people have been forced to flee their homes as a result of war, persecution and economic desperation. It's a migration crisis which is generating immense human misery and alarming levels of political discord. HARDtalk’s Stephen Sackur speaks to David Miliband - head of the US-based International Rescue Committee and a former British foreign secretary. Can this politician turned humanitarian explain why governments around the world are failing to meet the migration challenge?
