Panorama: Migrants Go Home

Reporter Paul Kenyon continues his journey out of Africa following
the route taken by 40,000 migrants a year seeking a better life in
Europe. He discovers the way to the UK blocked by a new hardline
policy in France to round up economic migrants and send them home,
and an unlikely partnership with Libya's Colonel Gaddafi, who has
reached an agreement with Italy to capture Europe-bound migrants at
sea and lock them up in desert prisons.

But what about those fleeing war and persecution, and relying on
Europe to protect them? Can it really justify handing them over to a
military dictatorship outside the rule of international law?
