I think proportionality is very important in any steps that you take. You mentioned about voluntary action. Certainly, the reason I brought forward the statement I did on NVZs was because, whilst I don't think the current voluntary sorts of schemes have worked in a way that we would want them to—and we've seen significant agricultural pollution of our rivers, for instance—I do think that, if you can work with the sector, it's much better than bringing forward legislation, and that's why I brought forward the statement I have. But, again, I will ask the Minister for Environment to raise it with NRW at her next regular meeting.
