Tim Llewellyn: This episode discredits the honest reporters the BBC still has on its books and in the field

Tim Llewellyn: These last weeks have exposed Israel as newly vulnerable, physically and politically.

For 10 years Tim Llewellyn was the BBC's Middle East correspondent. In this passionately argued polemic he accuses British broadcasters, including his former employer, of systematic bias in covering the Arab-Israeli conflict, giving undue prominence to the views of Jerusalem while disregarding the roots of the crisis.

Comment: ITC approval of John Pilger's documentary is a shot across the bows of mainstream Middle East coverage, writes Tim Llewellyn.
