I really doubt that many consciously ask whether something fits "the party line". They mostly introduce bias subconsciously in their decisions about what is and isn't "news". Politician A accidentally says something stupid and it's ignored. Politician B accidentally says something stupid and it's "Politician B's Latest Gaffe" on the front page. (Why yes, I do have a specific Politican B in mind, but shan't mention any names to avoid off-topic discussions.) Anyway, it's odd that you would think that being a "non-corporate news provider" would insulate the BBC from bias. What about the natural groupthink which tends to accumulate in organizations insulated from real-world concerns?
