Can I thank the Minister for that response? We have problems with a number of non-native species, but in my part of the world, Japanese knotweed is far and away the most problematic. Can the Cabinet Secretary provide an update on the trials that are taking place with the natural predator—I note you avoided trying to pronounce its name as well; I'm doing the same—and any progress with chemical treatments, because it really does cause a blight on houses, on areas, and makes houses unsaleable, and makes some of them dangerous?
