This is a must-read article. Oh yes.
Besides the furore over bungled BBC journalism, 28 Gate - the Beeb's refusal to name the "scientific experts" who convinced the broadcaster to take a firmly warmist position when reporting climate change - is far more profoundly serious than the BBC and its critics yet realise.
What a humble freedom-of-information request has exposed, and called into the question, is the conduct and judgement of the BBC Trust itself. The trust is the BBC's governing body; it's essentially the old Board of Governors given a Strategy Boutique-style New Labour makeover when Auntie's royal charter was rewritten.
The trust is the BBC's firewall: when things go wrong at the Beeb, it could always promise to step in, with talk about new brooms and fresh starts. But when the trust is found wanting, there is no place to go except into the arms of the state or a regulator.
