I didn't say that the BBC is afraid to criticise the British government. But they're still biased when it comes to issues involving Britain. For example, when the UK had to leave the ERM, the BBC (and virtually all of the press) decided that it was easier to blame the Germans for not cutting their interest rates than to accept our own financial incompetence. Any discussions on the UK's EU rebate are quite noticeably from the British pespective, and any comments on how the rebate is viewed in other EU countries tends to be an afterthought. And nothing visibly cheers a BBC economics correspondent more than finding some indication that the UK economy is oputperforming, by some indicator or another, the other principle economies of Europe.
Actually, the radio cricket commentators are pretty impartial, just to spoil the rule (e.g. their delight in the West Indies last wicket stand to beat England in a one day final last year - they were just keen to recognise good cricket). The football, athletics, rugby, golf, and tennis commentators on the BBC are biased, and, I'm fairly sure, are instructed to be so.
