So how damming must the Balen Report have been about the BBC's anti Israel bias?

This from Biased BBC caught my eye:

'In 2005, an independent report commissioned by the BBC's board of governors found that the corporation was guilty of "cultural and unintentional bias" in coverage of Europe.'

If that report into the BBC's coverage of Europe was OK to be released, can you imagine how damming the Balen Report into the BBC's coverage of Israel and the Middle East must have been for the BBC to fight tooth and nail to keep it secret?
