Israel's Livni calls on Olmert to step down

The announcement came a day after Israel's attorney general said he was considering filing charges against Prime Minister Ehud Olmert for allegedly double billing Jewish groups for trips abroad. He wants Olmert to appear at a special hearing before making a final decision on whether to prosecute and put Olmert on trial.

Olmert has already said that he will step down after elections scheduled in February. But at a meeting of the ruling Kadima party Thursday, Livni said he should go before that. His departure would clear the way for Livni to become acting prime minister until the election.

"The prime minister, like any other person in Israel, is innocent until proven guilty. But the citizen Ehud Olmert must wage his battle to prove his innocence from his home and not from the chair of the prime minister," Livni said, at special party meeting she called.

"The prime minister has to go on vacation, there is no other option," she said.

Olmert's office did not react, but has said that the prime minister plans to stay in office until the elections.

Livni was recently elected to succeed Olmert as Kadima leader. After initial polls showed her running neck-and-neck with opposition leader Benjamin Netanyahu, Livni has recently dropped far behind him.

Her attack on Olmert, who is widely unpopular, may have been an attempt to jump start her faltering campaign.

The double billing scandal is one of a half-dozen corruption affairs Olmert has had to face during his nearly three years in power. Olmert also has been accused of improperly taking tens of thousands of dollars from a U.S. businessman, involvement in questionable real estate deals and making controversial political appointments.

If Attorney General Meni Mazuz decides to file charges, Olmert would become the first Israeli prime minister to ever be indicted.
