Shortly after this development, a planned session of parliament was postponed until April 22. The extra time would allow further political discussions on this issue.
Leaders of the Shi'ite-led United Iraqi Alliance are also set to meet on April 22 to vote on whether to keep al-Ja'fari as their nominee for that post.
Al-Ja'fari faces strict opposition from Kurdish and Sunni parties, who blame him for failing to end sectarian violence.
