I welcome the debate; it is excellent that my hon. Friend has secured it. There is another issue that we need to explore in relation to the supply chain, and that is the enforcement of regulations. In my constituency, silage from farms is covered with black cellophane. That is, effectively, being exported to China, where it may potentially be dealt with inappropriately, when it is needed here for plastic recycling, to be turned into bin bags. We would be greatly aided in tackling that by the enforcement of existing DEFRA regulations. I know that Lord Henley is busy working on that, but we would welcome consistency and long-term planning on that front.
