As noted by David P. on the last open thread, a fine article about BBC bias by Simon Jenkins in the Guardian includes a remarkable passing comment about the BBC's director-general:
After the Brexit vote last June, Robinson’s boss, Lord Hall, went round the London dinner circuit wailing that BBC balance had “lost us the election”. It had given too much credibility to leave.
It's the first I'd heard of that. Has it been reported elsewhere?
If Lord Hall did behave like that then that's surely a serious breach of BBC impartiality by the corporation's editor-in-chief.
Or am I missing something?
