Kurdish negotiator Mahmud Othman said the Kurdish grouping in parliament had made known its views at a meeting on April 9 with representatives of al-Ja'fari's party.
The main Shi'ite alliance, the United Iraqi Alliance (UIA), has nominated al-Ja'fari to the post, but Kurdish and Sunni figures accuse him of failing to stop the wave of sectarian violence in Iraq.
The UIA on April 9 formed a committee to decide the fate of al-Ja'fari and end a standoff that has left a power vacuum nearly four months after the elections.
The U.S. ambassador to Iraq, Zalmay Khalilzad, on April 9 urged the world to be patient, saying the Iraqi people must not get just any government, but a good government.
