Can I thank the First Minister for that response? Knotweed is a serious problem in Swansea, especially in my constituency, but I'm sure Julie James could tell you exactly the same for Swansea West as well. Whilst the experiment with a natural predator and improved chemical treatments are to be welcomed, we have areas of green wedge where knotweed has become a problem. Has the Welsh Government got any plans of stopping green-wedge land becoming fully infested by knotweed, so instead of being a green belt, it'll be a knotweed belt?
