I thank the Minister for his answer. I'm sure that the residents of Newport will be pleased to see further progress in this area, and a proposal that will alleviate the congestion in the area while at the same time respecting the Senedd's commitment to reducing our carbon output.

Now, Minister, last week, Boris Johnson said that his UK Government intends to allow a bypass to be built over the Gwent levels. The decision about the bypass is a devolved matter and the Welsh Government, as you will know, took the decision last year that it would not be built on cost and environment grounds, following years of debate in this Senedd Chamber. It's perfectly clear to me that the UK Government would not be able to change this decision without introducing legislation in Westminster, overturning the relevant sections of the Government of Wales Act 2006. Could you tell me, Minister, what is the Welsh Government's analysis of the Prime Minister's threat? Do you think that he is serious about dismantling devolution, or is it your view that he was simply speaking off the cuff, displaying his famed ignorance one again? And can you give me an assurance that, were the UK Government to attempt to do this, the Welsh Government would be ready and willing to take the UK Government to the Supreme Court to prevent them from overturning Welsh democracy through diktat?
