It's amusing to watch BBC Head of Drama trying to wriggle out of the crisis of his own making. He'll soon be producing his family at the garden gate Little Britain style and uttering the famous words "what I meant to say was..."
He's under fire for saying the the BBC should "foster... left of centre thinking." He's now saying he actually meant "leftfield" rather than leftwing. It's possible he really did mean that, but the fact that this was said in a written article rather than an off the cuff speech tends to give weight to a more cynical reading of his words. When BBC executives write articles they are usually circulated to several others for approval. The fact that this got through that system without being changed says a lot.
Laughably, they are now saying that because Boris is appearing in an episode of East Enders it proves there is no bias at the BBC. ROFL.
