Just a quick passing note as I'm rushing off:
The Conservative Party hate the BBC. They probably won't campaign openly on a 'shut the BEEB' ticket, but you can expect Auntie to be in something close to the position that PBS holds in the US after a reasonably short period of Conservative government.
The problem is that their position will go down reasonably well with a sizeable section of the paid commentariat, and Tory activists love it.
The Tories won't break cover and declare open hostility to the corporation in advance of the election either - yet I'd be inclined to believe that their approach to the BBC - if expressed honestly and openly - would be terrifically unpopular.
