Across the globe an estimated forty million people are victims of modern day slavery, either in forced labour or forced marriages. Devina Gupta and her guests in Delhi discuss what can be done to end this. In India alone around 18 million people live in modern slavery, according to the Global Slavery Index - although that statistic is questioned by the Indian government. Joining Devina to explore the reality of this hidden world are Riya Singh, a young female activist who works to end oppression in India's unique caste system; Manoj Bhatt, country director, GoodWeave, an organisation that tries to spread awareness about slave labour in the global supply chain; and Colin Gonsalves, a senior advocate in India's top court, whose organisation rescues forced labour. In the Balance is produced this week in conjunction with the Work Life India team.
