I thank the Member for his question. I know you've been vociferous in representing your constituents and communities in raising this area, and you're right, it does cast a blight on our buildings and on our local environment. I do notice I get the formal words for these—it does take you a while to get your tongue round some of them. I'm learning quickly on that.

You asked about the data in terms of the trial. Swansea University is currently analysing the data from their initial two-year chemical control trial, with the aim of producing technical advice to help tackle Japanese knotweed. I look forward to reading the final report, as I'm sure the Member will look forward to too. I can also confirm that the Welsh Government has provided additional funding for the Centre for Agriculture and Biosciences International to continue the psyllid project for 2017-18.
