Speaking to BBC2's Newsnight, the BBC's acting Director General Tim Davie said it had been a "bad and sorry saga", but defended the lack of sackings.
My job is not to just dismiss people, my job is to make a fair and balanced assessment of the facts. We have lost a Director General in this process.
We all need to accept change and the only way to change is to change the culture, and that's not going to be done however many people we call to be dismissed.
It's going to be done by people like me leading the organisation and changing the culture. I want a change of culture, that is what I am all about.
