Re: do we need the BBC.
Yes we need the BBC. It's general outpuit of TV and radio programming would be sorely missed.
It has however in recent years as the internet, Digital TV and Digital radio has become available, possibly exceeded it's remit, trying to cover every niche area. There are grounds for it to be scaled back.
As to how it should be funded, that is not the title of this thread and vote, and thus is irrelevant to my answer.
