The buck stops where?

Did you see the Schools Secretary, Ed Balls, giving a classic "not me Miss, please Miss" performance on Channel4 News the other night when being questioned about the SATS shambles? He's adopted the clever trick of putting another body (the Qualification and Curriculum Authority) between himself and what's actually going on, so that if it all goes pear-shaped (which it has) he can lay the responsibility at their door, rather than have to accept it himself. Of course, you can guess who appoints the members of the Authority, can't you?
