Eighteen political lists in Iraq, including those of nationalist Shiite cleric Muqtada al-Sadr and outgoing Prime Minister Haider al-Abadi, have come to an agreement to form largest parliament bloc capable of forming a new government.
The bloc consists of 184 deputies, which is above the number needed for a majority.
Meanwhile, the leader of the State of Law Coalition, former Prime Minister Nouri al-Maliki, has announced a bloc called "al-Bina," which he claimed included 145 deputies.
It was unclear as of Monday morning whether the KDP and PUK would joing with the Sadr-Abadi group or the Amiri-Maliki group.
The two parties met recently with officials from Amiri's Fateh Alliance.
The Council of Representatives is set to convene on Monday when the new parliamentarians are scheduled to elect a new speaker, which sets the stage for a new president to be chosen.
