LONDON — BBC governors are to poll U.K. viewers about whether they feel the pubcaster’s programs are biased in light of its controversial coverage of the Iraq war.BBC director general Greg Dyke recently rejected charges that the BBC’ was soft on Iraqi leader Saddam Hussein during the conflict. Opposition leader of the Conservative Party, Iain Duncan Smith, has also accused the BBC of bias against the Conservatives. The governors announced Tuesday that they plan to produce a quarterly report based on audience opinions about BBC’s impartiality and the findings will be published in its annual report. “One of the core responsibilities of the governors is to look at impartiality. After a conflict, that is particularly important,” said a BBC spokesperson.
