In preparation for this debate, I read the 'Clean Air Plan for Wales' consultation document, and I also had a meeting with Public Health Wales to talk through some of the issues that are in the motion. And having done that, framing Public Health Wales as independent experts, I don't share the pessimism of Plaid Cymru, but I do welcome some of the words that are in the motion. So, I support the thrust of the motion but I don't feel as pessimistic, and I reflect on Jenny Rathbone's optimism, actually, that the Welsh Government will engage and have a clean air Act before the end of this Assembly term. I think that's likely to happen.
