Greg Dyke, the BBC's director general, has attacked American television reporting of Iraq. "For anynews organisation to act as a cheerleader for government is to undermine your credibility," he said."They should be... balancing their coverage, not banging the drum for one side or the other." Hesaid research showed that, of 840 experts interviewed on American news programmes during the invasion of Iraq,only four opposed the war. "If that were true in Britain, the BBC would have failed in its duty."
