Thank you very much. I don't mean to cut you off, but I'm subject to time constraints.
Mr. Smith, may I ask you a question about what we heard at the outset of the answer from Mr. Evans' supply chain investigation? Can you go into that again? It seems to me that it would be tremendously complex to really understand all the touchpoints in a supply chain. How do you carry out such a process? It seems incredibly complicated to investigate the entire supply chain to ensure that modern slavery isn't being carried out.
I think, for example, of fair trade, which is a welcomed initiative as far as international trade goes, but we know that all too often, perhaps in most cases, what is marketed as fair trade has not been developed in a fair way at all, that there is exploitation well in the process, early on in the process, in the middle of the process, and towards the end of the process. You see how it would be difficult to understand, from my perspective and, I think, the perspective of others as well, about the supply chain and the challenges of monitoring it.
