The ECP will now meet again tomorrow (Sunday) to finalise a name for a caretaker PM.
Speaking to the media earlier in the day, ECP Secretary Ishtiaq Ahmed said the commission has two days for the task and it will do it by tomorrow if not today.
ECP member from Sindh Rosha Ehsani failed to show up in the meeting because of ill health.
The meeting, headed by the Chief Election Commissioner Fakhrudin G Ebrahim, constituted members from Punjab, Balochistan and Khyber Pakhtunkhwa.
The matter fell in the hands of the ECP after an eight-member parliamentary committee formed for the task failed to reach a decision.
The four nominees for the post of an interim PM are: names are Ishrat Hussain, Justice (retd) Nasir Aslam Zahid, Rasool Bakhsh Palijo and Mir Hazar Khan Khoso.
The commission is supposed to make a decision within two days, and if it failed to do so, the choice of majority would be considered.
