A party official says partial results from Israel's Labor Party primary election shows no clear winner, meaning the two front-runners will compete next week.
Labor was once the major force in Israeli politics but has lost much of its power.
Labor's election committee chairman Raanan Cohen gave the results early Tuesday after 80 percent of the votes had been counted.
Former journalist Shelly Yachimovich and Amir Peretz, who served a short stint as defense minister, were in the lead with a little over 30 percent of the votes each. Isaac Herzog, a former Cabinet minister, came in a close third.
A candidate needed 40 percent to win, otherwise the top two candidates compete in a Sept. 21 runoff.
Official results were scheduled to be released later Tuesday.
