Chairman of the BBC Trust Lord Patten has said the Pollard review transcripts made public today by the corporation paint a "very unhappy picture".
He said in statement: "These documents paint a very unhappy picture, but theBBC needs to be open - more open than others would be - in confronting thefacts that lie behind Nick Pollard's report.
"A limited amount of text has been blacked out for legal reasons, but no one could say that the effect has been to sanitise this material, which again puts a spotlight on some of our failings. We need to acknowledge these shortcomings and learn from them."
