Maybe the BBC was too left wing for the former Commies.
Very possibly, and also far too corrupt even for Commies:
BBC admits fake winners on charity appeals (staffers posed as winning callers on air)
BBC BOSS TAKES A BITE (Director General of the BBC bit colleague on the arm 17 years ago)
BBC in row over doctored TV footage with Gordon Brown (....made him look like a thug)
BBC may be prosecuted for offering £40,000 to 'child-smugglers' (story faked)
Craven at the BBC (Islam treated with fawning reverence, Christianity with near-disdain)
Former? When did the "epiphany" take place. News to me.
