Thank you for that answer, First Minister. I'd like to return you briefly to the issue of road congestion and the impact on climate change. I very much welcome the consideration that's now being given to the issue of congestion and pollution from traffic into Cardiff. Of course, that traffic doesn't miraculously appear in Cardiff, it goes through constituencies such as mine into Cardiff, and that congestion and pollution is felt all through quite a large number of our constituencies. But, in particular, the solution to congestion and pollution is not just in Cardiff, it lies much further through.

In order to win the support, I think, of the many people in the Pontypridd constituency and further afield, it seems to me that consideration of the whole issue of congestion charging is dependent on a number of principled assurances I think people want. The first one is that the costs do not disproportionately fall on the poorest communities. The second one is that a proportion of the proceeds are redistributed and invested within our broader transport system. And that, thirdly, there is an affordable public transport alternative available, First Minister.
