It's not unusual for commitments made by parties and governments to change over time, and often they are changed as a consequence of an evaluation of value for money for those interventions that are promised. The electrification—I don't want to be political, but I must say that the question about the electrification of the south Wales line and the cancellation of that programme was put down to the value for money for that particular project, and the argument made by the Department for Transport that, actually, new technology could offer the same improvements and the same time savings as overhead electrification. So, it's not unusual for manifesto pledges to change over time as new technology and as fuller consideration of value for money is made.

In terms of the M4 around Newport, our proposal was the black route—that was what we were pursuing and promoting. However, now that the decision has been made not to proceed with that particular solution, we are examining all short-term measures that are available to alleviate congestion. I'm pleased that we are able to introduce additional patrol services and breakdown recovery services. These will not come without cost; these are expensive services, but they are tried and tested. They were deployed first on the A55 as part of the A55 resilience programme, and they are proven to work. That's why I was able to say last week, when the decision was made by the First Minister, that we would be able to deploy that particular solution with immediate effect.
