Thank you very much, Cefin. As I said, the service is under immense pressure at the moment. The increase in the number of people calling for ambulance services—well, we've never seen anything like this before. The fact is that about 20 per cent of those calls relate to COVID, so it is a period of immense pressure. The rostering—that's the change that's being made at the moment; rethinking about where ambulances will be located. A lot of work has been done on that. I do hope that there will be an opportunity for you to attend on Friday to listen to the ambulance service explaining what they're doing, why they're doing it and why they're responding in this way. So, there will be an opportunity for you then to ask more specific questions, such as the ones that you've asked this afternoon.
