On that particular point about targeted interoperable radiotherapy, I too have spoken to these professors, and I understand where they are in the clearance process. I find it a little bit concerning when there is a lack of money in the system. Is my hon. Friend aware that there are half a dozen machines around the country that could deliver that targeted therapy? Perhaps we need to look at what we should do first—whether it is purchasing the machines or giving the clearance in full.
