Yes, absolutely. I mentioned yesterday that I was a child of the 1960s and I remember DRSs, but I think that things have moved a great deal since then, and, in Wales, we recycle 75 per cent of our plastic bottles. We have excellent kerbside recycling, so you must make sure that there are no unintended consequences or outcomes in relation to having a DRS. But absolutely, the cost to the household has to be part of the analysis as to whether we take this forward.
