Mr David Nicholson.
For a period of his life this person was in charge of Stafford Hospital where patients were dying through lack of care. Did he do anything about it? Not a chance, by his own admission he was so far removed from the coal face and working through intermediaries that he had no idea about what was going on. He now says that, with hindsight, he would have done things differently.
Sorry sunbeam, but we don't pay for people to manage with hindsight we pay for their foresight.
As for his being "grilled" by MPs, as reported by the BBC, what a joke. He was treated with kid gloves when compared to a real grilling. Not once was he truly pulled up and asked to explain. If his performance was woeful and an insult, and it was, the performance of the MPs was worse.
