"As part of our initiative to identify and mitigate risk, we have in place systems to assess whether particular relationships or transactions are susceptible to slavery and human trafficking. As part of this process, we contact key suppliers to outline our requirements in this area and reinforce the important role they play in ensuring we deliver on our commitments. We monitor the performance of our suppliers in this respect and have effective reporting systems in place to protect employees, or other parties, who raise concerns about any breach of our Anti-slavery and Human Trafficking Policy."
