The dreaded Japanese knotweed extends beyond Swansea East and into other parts of South Wales West, including areas around railway lines and areas that have been identified in the draft local development plan for quite extensive development. I'm wondering if you could commit today to speak to your Cabinet colleagues across the relevant portfolios to try and establish what the cost would be, particularly to the Swansea bay metro plans, such as they are, and to the plans under the LDP, should the knotweed blight not be controlled. I think there's some significant concern starting now, particularly around the railway lines, around potential plans for a metro, because getting rid of that stuff first has got to be dealt with before we can even think about expanding the rail network. Thank you.
