I endorse everything that my hon. Friend has said about the mobile stroke unit. I encourage the Minister to look at the great success that it has been. As my hon. Friend knows, I have particularly focused on the transport issues. The East of England Ambulance Service, which would be the logical service to provide that transfer, is under great pressure as it is. Does my hon. Friend accept that if the whole of the STP is to stand up and be coherent, we must have clearer answers about exactly how the transfer of critically ill patients from one hospital to another would work in practice?
