I've been made aware of recent examples in Swansea where patients—well, one patient had to wait three and a half hours with an urgent situation for an ambulance, and another patient waited four hours having suffered a myocardial infarction. Still at home, they waited four hours for an ambulance to attend the scene. Another patient waited five hours for an ambulance to attend the scene in the community. On top of that, I'm aware of people having to wait on trolleys for over 20 hours in accident and emergency, having had a heart attack as well. Now, I take on board all that's been said so far, that this is obviously about improving patient flows through hospitals, and naturally I'm aware that much good work is being done, and in all these cases that I've outlined, there is nothing but the highest praise for the nurses and doctors involved in the cases. But those waits remain. So, what in addition can you do to address matters?
