First Minister, this is a very serious issue. When the Public Health (Wales) Bill was going through its passages in the committees, we had some very compelling evidence from many companies and organisations about how we could tackle air pollution and how we could improve the quality of air. Your Government chose not to take those recommendations forward, despite some of the committee recommendations. Given the severity of the World Health Organization's report, can I ask you if you intend to revisit the Public Health (Wales) Bill? And will you ask your Minister to review, again, the evidence that we took, and the recommendations we made, to see if now might be a more appropriate time for your Government to actually take action?
