Israel‘s Labor Party will go to a run-off round to determine who will be its new leader. None of the five candidates in Monday’s election was able to reach the 40% threshold, obviating a second round. Ehud Barak, a former prime minister, and Ami Ayalon, a former head of Israel‘s navy and Shin Bet domestic security agency, will go head-to-head on June 12 for the party’s top spot and a chance to become prime minister if Labor takes the most seats in the next general election. The election has garnered an unusual amount of international attention because many see it as the beginning of the end of Prime Minister Ehud Olmert’s tenure if the new Labor chief takes the party out of the ruling coalition. Ayalon has said he will not allow the party to sit in a government headed by Olmert, who is under intense criticism because of last summer’s war in Lebanon. But analysts at The Media Line point out that Olmert has other parties available to him – right wing and religious – that could fill-in to a degree that would allow his government to limp onward.
