JERUSALEM (AP) – The campaign to oust Prime Minister Ehud Olmert shifted to the streets Thursday, with a mass rally in Tel Aviv expected to draw tens of thousands of opponents calling for the embattled Israeli leader to step down.

Mr. Olmert, under fire for his handling of last summer’s war against Lebanese guerrillas, appeared to be quashing an incipient rebellion against him in the ranks of his Kadima Party – at least for now.

On Wednesday, Foreign Minister Tzipi Livni, a party heavyweight, called on him to quit, and another top party figure, parliamentary coalition chief Avigdor Yitzhaki, resigned to protest Olmert’s refusal to step down.

But other Kadima officials rallied around their beleaguered chief, no doubt mindful that a widespread mutiny could lead to early elections that could land the party on the skids. Polls indicate hawkish former Prime Minister Benjamin Netanyahu, leader of the opposition Likud Party, would win if new elections were held.

Mr. Olmert himself said he intended to stay on to remedy the severe flaws in decision-making and crisis management that a government war probe identified in a scathing report released Monday. Mr. Olmert was singled out in the report for exceptional censure.

At an emergency Kadima meeting called after Ms. Livni’s announcement Wednesday, Mr. Olmert said he would implement the war report’s recommendations “down to the last detail.”

“I’m personally in an uncomfortable position, but I’m over 60, and have had a lot of experience,” spokesman Jacob Galanti quoted him as saying. “I’ve learned to take responsibility for my actions.”

Israel’s parliament was to interrupt its spring recess Thursday to hold a special session to discuss the war probe.

Ahead of that session, Mr. Netanyahu added his voice to the chorus of calls demanding Mr. Olmert’s resignation, and appealed for new elections.

“It’s clear to all that this government lost the last scrap of public trust, if it ever had any,” he told Army Radio. “It’s clear to all that it should return to the people and let them speak their minds.”

Hostilities erupted on July 12 when Hezbollah guerrillas crossed into Israel, killed three soldiers and captured two others.

In 34 days of fighting, Israel failed to achieve the two main goals Mr. Olmert set: to return the soldiers and crush Hezbollah. Instead, Hezbollah fired nearly 4,000 rockets into northern Israel.

Nearly 160 Israelis and more than 1,000 Lebanese died in the fighting, and Israeli soldiers returned from battle complaining of conflicting orders and shortages of food and ammunition.

Opinion polls released Wednesday show two out of three Israelis want Mr. Olmert out now.

In defecting from Mr. Olmert’s camp, Ms. Livni – a popular figure in Kadima – told the prime minister he had lost the public’s support, and said she considered herself the rightful successor to lead Kadima.

“I told him that resignation would be the right thing for him to do,” Ms, Livni told reporters. “I haven’t worked and am not working to topple the prime minister. That’s a decision he’ll have to make.”

Ms. Livni – a relative political newcomer and a former officer in the Mossad spy agency – is Kadima’s most popular politician. The daughter of an underground fighter who fought for Israel’s independence, she has quickly risen through Israeli politics in recent years and appears to be Kadima’s best hope of retaining power.

Under Israel’s parliamentary system, Kadima could switch its leader without losing power. The Israeli prime minister is not directly elected and usually comes from parliament’s largest bloc.

But Vice Premier Shimon Peres, emerging from the Kadima meeting late Wednesday, said the party backed Mr. Olmert in his decision not to resign.

“The prime minister received here unprecedented support,” Mr. Peres told reporters.
MoReuven Hazan, a political scientist at the Hebrew University of Jerusalem, said Ms. Livni’s challenge would have been worse had she threatened to resign or bring down the government.

“We see a ball rolling, but a ball that could have taken on a lot of momentum today has slowed down,” he said.

Mr. Hazan said the turnout by Mr. Olmert’s opponents at the rally in Tel Aviv on Thursday could determine whether the momentum against Mr. Olmert grows or fizzles out.

Lawmakers Effie Eitam, a hawk, and Yossi Beilin, a dove, set aside their deep political differences to team up in a joint newspaper column on Thursday, demanding a shakeup at the top. They predicted hundreds of thousands of Israelis would show up in Tel Aviv to call for a new leader.

“Both of us are convinced Olmert has to go home because of his great failure during the second Lebanon war,” they wrote in the column that appeared in the Maariv daily.

Alon Davidi and 34 other protesters started marching to Tel Aviv two days ago from the southern town of Sderot, 45 miles away.

“We want as many people as possible to come to the square and say, ‘Ehud Olmert go home,’ ‘(Defense Minister) Amir Peretz go home,'” Mr. Davidi told Army Radio.

Sderot is Mr. Peretz’s hometown, and the frequent target of Palestinian Arab rocket attacks.
