So, Sir Gus O’Donnell is to be the new Cabinet Secretary. So much for the fiction that the civil service wants to recognise and promote civil servants who "deliver" public services. Gus is a great guy, and is no doubt a good policy adviser. But he has never delivered a public service – except advice – in his entire life. As ever, the rhetoric about what sort of skills we will value in the civil service is somewhat different from the reality.
