Can I thank Alun Davies for his questions? I do recognise the frustration that many people across the region feel. This is a problem that has affected south-east Wales for decades, and it's a problem that we are determined to get to grips with and to solve. That's why we've appointed Lord Burns to chair a commission of experts. That's why I have great confidence in the commission to be able to propose solutions that will lead to reduced congestion and as near as possible to free-flow traffic. 

I've already identified the timescale for the work that will take place, and we have informed the commission chair that we would wish to see immediate interventions produced in their interim report, if not sooner, as I have said to Russell George. And the purpose of the commission's work is crystal clear: it's to identify deliverable alternatives that offer value for money to the black route scheme that will reduce congestion to a level as close as possible to enable free-flow traffic to take place.

Now, of course, each and every suggestion and proposal that are presented by the commission will be scrutinised by Ministers for the deliverability and value for money that they present, but given that we are appointing traffic experts or transport experts to the commission, I have every confidence in them proposing deliverable and affordable solutions within that six-month time period.
