Asif Ali Zardari took control of Bhutto's party after her December assassination. The party won last month's elections and now dominates parliament.
Zardari was charged in 2002 with playing a role in the murder of Nizam Din and his son. The men were shot to death in Karachi in 1996.
Prosecutor Naimatullah Randhawa said Monday a court acquitted Zardari "due to lack of evidence."
Parliament was set to elect a longtime Bhutto aide as prime minister on Monday.
