BBC bosses were in the spotlight yesterday when seven of them were asked to appear before the Commons Public Accounts Committee to answer a few questions about the BBC's imprudent use of licence payers' money.

One very important boss, the current Director-General Tony Hall, seemed to be keeping a distinctly low profile. It was, by the way, essentially Chris Patten's decision to offer the director-generalship to Tony Hall after his previous nominee failed to deliver. So why, on such an important day for the BBC, did Lord Hall not surface to give interviews to programmes like Channel 4 News and Newsnight?
