British actress Julia Ormond has called upon international law enforcement agencies to work together to end human trafficking. The Legends of the Fall star, who has been involved in the fight against modern day slavery for over a decade, spoke on behalf of a United Nations campaign to stamp out the global issue. The drive comes as Britain marks its 200th anniversary of abolishing slavery. Ormond, 42, says, "What we do know is that the statistics are the tip of the iceberg." She adds global agencies must begin to "apply anti-trafficking laws equally - that's the crucial part".
