Bhutto's husband or top aide may take over
It's believed the next leader will either be Bhutto's husband, her son or her top aide.
The party's leadership is also deciding whether to contest January's election – if it goes ahead. Continuing violence in the wake of the murder has thrown next month's ballot into doubt.
Benazir Bhutto was killed on Thursday when a suicide bomber opened fire after an opposition rally in the Pakistani city of Rawalpindi. One report says she died from bullet wounds. Another says she died after hitting her head on a car sun roof after the suicide blast.
The incident has sparked waves of violence across the country. More than forty people have died so far.
The Pakistani authorities said Bhutto's body could be exhumed for further investigation.
