Now, further evidence of the lack of prioritisation that you have given to air pollution is the budget for 2021-22. You admitted to our Climate Change, Environment and Rural Affairs Committee that there is still no detailed cost estimate of the clean air plan that was published seven months ago. The £3.4 million revenue funding and £17 million capital funding allocated for air quality action actually remains unchanged from the previous year, and therefore represents a real-terms cut.

In fact, I know that this is not the first time that this has been raised with you, as you were scrutinised on the matter during committee in January, blowing the concerns about funding to one side by informing us again that you have competing priorities in the budget and, of course, the impact of COVID-19. As you know, I acknowledge that challenge, but I still need you to explain why there is no detailed cost estimate for this plan, and what led you to make a political decision to deprioritise the health crisis caused by air pollution by delivering a real-terms cut in funding.
