My 2 comments below are a tad late as I've just returned from holidaying in France.
1. Blair's interview with Marr was more of an 'Audience with' with soft questions and no tricky follow up answers. Blair was allowed to promote his own agenda and hog the lime light and milk the occasion to promote himself.
2. So Mark Thompson admits the BBC had a left wing bias which in his opinion it no longer has!!!!
Pull the other one Mark - the BBC is INSTITUTIONALLY biased to the left as the many blogs on the subject testify.
