First Minister, thank you for the response to John Griffiths there. Obviously, he represents a Newport constituency, where the M4 relief road could have been such a piece of major infrastructure. The alternatives to an M4 relief road I think are due to be presented to you shortly, and I imagine that you've already been given a rough indication of the cost of those alternatives. What is the range of those rough costs, and what have you done to secure any necessary Treasury support, having refused that support when, of course, you ditched the plan for the M4 relief road?
