I thank the Member for his question and his interest in this area. He raises a very important issue. Any incident of pollution in our rivers is one incident too many, for a variety of reasons, which is why this Government has taken action in terms of how we tackle agricultural pollution. We know that the vast majority of people adhere to best practice, and it's the minority that create these incidents that we are taking action to combat. Just this week, my colleague the Cabinet Secretary for Energy, Planning and Rural Affairs—I forgot her title for a moment then—announced further investment for the sustainable production grant, which is to support the delivery of environmental outcomes, including on agricultural pollution, and provide support for farmers facing the considerable challenges of Brexit. So, that's just one step. 

We're also working with—. Of course, pollution doesn't just refer to slurry. It could be litter and other contamination in our rivers, and that's why we work with organisations such as Keep Wales Tidy and Groundwork Wales to tackle that as well.
