Andrew Forrest is the Chairman and founder of Fortescue Metals Group, the world’s fourth largest iron ore producer. He is also the Chairman and founder of the Walk Free Foundation, an organisation committed to ending all forms of modern slavery by mobilising a global activist movement, generating high quality research, enlisting business and governments to drive change in those countries and industries where slavery is most prevalent today. We asked Mr Forrest to explain why eradicating modern slavery is an issue for business and to share his insights on what it means to ensure that the complex, international supply chain of a leading company is free of modern slavery.
