My hon. Friend is being very generous with his time. He has hit the nail on the head: the treatment is very specialist and is carried out by surgeons and neurologists who are not normally there to treat stroke victims. The change in the way in which stroke centres work has been fantastic. Stroke services have been centralised, but we need to go a step further and to make sure that we get the right training for these neurologists so that we can continue to save lives.
