Well, I thank Mike Hedges for that further question. I think these are really important issues that deserve to be more thoroughly and regularly publicly aired. There's good news, I think, in responding to him: the note that I have tells me that atrazine, hexachlorobenzene and methomyl are already banned for use in the United Kingdom and here in Wales. Rotenone has its use limited now to dealing only with invasive fish species, and I think that probably points to the dilemma at the heart of the debate that Mike Hedges has opened for us this afternoon, which is, while pesticides can cause harm, sometimes there are genuine uses for them that prevent even larger harm, and dealing with invasive species is one of the ways in which those powerful chemical pesticides can still have a beneficial use.

Glyphosate is the most commonly used of the pesticides that Mike Hedges referred to. We have up until now followed the rules used in the European Union. The European Union extended its existing permissions for the use of glyphosate for a further 12 months in November of last year, and it's expected that they will issue fresh advice on that before the end of this calendar year. That will feed into a new United Kingdom national action plan for sustainable use of pesticides. We're expecting that by the middle of 2023.

Wales can go further than that plan if we are not satisfied with its scope, and I very much agree with the point that Mike Hedges made towards the end of his supplementary question: in the policy world that surrounds pesticides, they talk of three different use classes. There is agriculture, there is amateur use—you can buy glyphosate in any garden centre—and then there is amenity use, the use of such pesticides by local authorities and others. That's the area that I am keen that we focus on. I don't believe there is a case for using that sort of chemical, for example, on a school playing field, but we don't yet have a rulebook in Wales that prevents that from happening. There's a great deal of good work that goes on to reduce the use of pesticides in that way; there are opportunities in this calendar year to make that more formally part of the system that we have in Wales.
