Here is an example of the very subtle way the BBC is bias in its news reporting.
The news on Radio 2 at 5pm lead obviously lead with the Spending Review but had NO extract of George Osbourne's speech ( the main event let's face it!) but did manage an extract from Alan Johnston and choose the most class conscience comment of the lot which was that in his opinion many of the Conservatives sole agenda was an ideological crusade to cut welfare spending.
This is very bias.
Fairness would have had a quote from each and certainly not the most class conscience comment forn Alan Johnston on its own.
