A little while ago I blogged about a film on Newsnight about Gordon Brown.
Interestingly, the assembly of that film has now been called into question. The sequence of a meeting between the filmmaker and a Treasury assistant was changed so it looked like one incident happened before another, when in fact it happened afterwards. (I would add that the BBC have also been criticised for not making clear that the security chief was not aware of being recorded when he accused Brown of being "shy and withdrawn". But as you can see from my blog posting, it was clear to me that the chief didn't know he was being recorded.)
It seems a relatively minor indiscretion but when you stack it up with the Queen film change, the Blue Peter faked quiz winner and the Quiz Show scandal it all mounts up to a major crisis for the BBC.
One can't help thinking that the culture of independent producers is to blame for much of the crisis.
