Seen as sectarian and divisive by many, the Shiite premier points to his huge popular mandate after his State of Law coalition dominated April's parliamentary elections.But his bid for re-election was dealt a blow by Osama al-Nujaifi, who held the speaker's position in the previous parliament and announced he would not seek a new tenure. The complex game of alliances being played over Iraq's top three posts means that, although the two men are rivals,Nujaifi's withdrawal is seen as removing a key obstacle to Maliki's ouster.
