I've just been libelled by Greg Philo of the Glasgow University Media Unit, who believes that the BBC is biased in favour of Israel.

Speaking on Radio 4's The Message, he accused me of making up the examples I have cited of BBC bias:

We checked all of the things that he had said and they were just false. We went back to the transcripts and checked what had actually been said and what he said was wrong.

As Prof Philo must know, if he has indeed checked the transcripts, that is a lie. I challenge him - or anyone - to point out a single example of an example I have cited being made up, or in any material way inaccurate. (By material I simply mean that there may be the odd definite article or 'um' left out.)

It is one thing to argue that none of my examples amount to bias because there is a generalised balance across BBC News, or that there is nothing wrong with having programmes having only one set of views portrayed. But it is an outright falsehood to argue that I have made any of my examples up or been in any way inaccurate in the reporting of them.

It's surely relevant that the tactics adopted by those who deny BBC bias appear to be outright lying or, in the case of the BBC's pathetic response to my Jewish Chronicle piece, not to respond in any way to specifics.
