The BBC Chairman was last night locked in crisis talks with the Director-General after thousands of viewers jammed the corporation's switchboard complaining about all sorts of stuff. Commentators say the huge backlash against the BBC's handling of one thing or another must now call into question the future of the licence fee itself. "The BBC is under an obligation to act impartially, but they are clearly completely biased either in favour or against whatever it is we are talking about," says one viewer. "Filth," he adds, sadly. "Absolute filth."
