Gillian Anderson campaigns against modern slavery

In an interview with the BBC's Andrew Marr, Hollywood actress Gillian Anderson has said that slavery is alive and well in every city in the world.

She said modern slavery was a $150bn business and urged governments and big business to do more to ensure there was no slave labour in supply chains.

She appeared with Monique Villa, CEO of Thomson Reuters Foundation and organiser of the international Trust Women Conference in London.

Ms Anderson also talked about her role in Sold, a film based on the true story of a survivor who was trafficked from Nepal to a Kolkata brothel as a young child.
