Well, this is an issue of obvious concern, not just to the wider public but to myself as well. I have seen and identified in the independent evaluation of the new clinical response model some concern about the boundaries of categorisation, between red and amber, as one issue that is being addressed by the emergency ambulance services committee and the Welsh ambulance services trust, in addition to the longer tail. Because whilst our average times are reasonable, there are too many people waiting too long. There are examples of people waiting significant amounts of time, so I have already asked the chief ambulance services commissioner to undertake a piece of work to understand why that is happening, and then also for our whole system to look at what needs to change to resolve that. Because overall, we actually provide a good service, and we should be proud of the improvements that we have chosen to make. Ninety-six per cent of people with suspected strokes received the appropriate care bundle—a significant improvement in the quality of care being provided. The average response to a stroke call is less than 14 minutes. But for some people, they wait too long. We should be honest about that, recognise that, and look to improve that. That's exactly what I've tasked the health service with doing.
