Diolch yn fawr, Llywydd. I'd like to turn to the subject of the performance of our emergency care system, and it's been highlighted that the performance of two out of the three of the accident and emergency units in hospitals in the Betsi Cadwaladr region has been so bad that it's dragged the average Welsh figures substantially down. The First Minister acknowledged last week that this level of performance was unacceptable. Now, given that the Minister is, through special measures, directly responsible for this performance, can he account for the factors that have led to it?
