Thank you, Trefnydd. You'll be aware, I'm sure, that there has been some coverage in the press and fierce opposition and local concerns about the consultation that took place over the summer on charging drivers to use the A470 between Upper Boat and Pontypridd and also on parts of the M4. I know that the Deputy Minister for Climate Change has stated on Twitter that there are no plans or discussions on charging drivers. But, could we have a statement on this, please, particularly in terms of what the Government's plans are to reduce the high level of pollution on this section of the A470, and they continue to be too high despite the speed limits that have already been put in place?
