I appreciate that the statement by the Minister today goes further than just responding to a legislative challenge, but I think it is—and needs to be put on the record—shameful that the Welsh Government has had to reach this point by dint of responding to a High Court case, and it's taken an awful long time because, a year ago now, Plaid Cymru actually sought to amend the public health Bill to put some of these features that are now in the Minister's announcement actually in our legislation. And I think that is the first thing that I'd like to identify as still missing from what the Minister has said today. So, Plaid Cymru are certainly of the view that we, by now, need a clean air Act, in effect, for Wales.
