A BBC investigation has found factory workers in Bangladesh are working 19-hour shifts in dangerous conditions to make clothes for Western high streets.

Secret filming by Panorama discovered that some factories hide the long hours from retailers by keeping two sets of books.

Richard Bilton reports.
