It has already claimed its first scalp, Entwhistle's. I doubt it will be the last, but will anything solve the underlying problem, the lack of standards and accountability that meant the Newsnight team felt they could get away with both this and the Saville coverup?

Any other channel would worry about losing viewers - hence revenue - or being fined by Ofcom, which would come straight out of their bottom line and upset the shareholders. Fining a atx-funded entity is an exercise in futility, though, and loss of viewers has no financial impact for the BBC unless they axe the series entirely. Maybe a few firings in this case will nudge the rest in the right direction for a while, but it's no long term solution.
