Diolch yn fawr, Llywydd. Can I pursue this point about the role plastics play in generating so much waste and destruction of our environment? Reference has been made to the excellent action of Iceland, and that supermarket actually conducted a very extensive survey before they took that action, and 80 per cent of the people they polled said they would endorse moves to go plastic free. I think, responding to such a public sentiment, the UK Government has committed to working with the Waste and Resources Action Programme to explore the introduction of, for instance, plastic-free supermarket aisles in which all the food is loose. I think we need this type of thinking. I wonder what plans you have to review the Towards Zero Waste programme to make it more ambitious and to reflect this growing public demand for action.
