Well, I'd be very disappointed if calls took over half an hour to respond to on a red call. As far as red calls are concerned, we are well above target. It's not 100 per cent—I understand that—but we're well above target in terms of ambulances reaching people when they are needed. There has been an issue that's been raised in terms of amber calls, of course. There are some patients who continue to wait longer than we would expect, and I know that the Cabinet Secretary for Health and Social Services has commissioned the chief ambulance services commissioner to look at the amber category, to conduct a clinically led review of the amber category. That does include serious but not life-threatening calls—around about almost two thirds of the call volume, actually, of the Welsh ambulance service. I know that that Cabinet Secretary will update Members over the course of the next few weeks.
