Jerusalem ? Prime Minister Ehud Olmert will face fierce criticism when a government commission releases its first findings today on last year’s inconclusive war in Lebanon, officials said, raising pressure on the Israeli leader to step down.

Leaked sections of findings prompted a new round of resignation calls Sunday from both the opposition and members of Olmert’s governing coalition.

Officials close to the investigation, confirming Israeli TV reports, said the report would be tough on both Olmert and Defense Minister Amir Peretz.

Among the findings are that both men made hasty and ill-judged decisions at the outset of the war, and these errors were compounded by their lack of experience and unfamiliarity with defense issues, the officials said.

Olmert reluctantly appointed the commission of inquiry in September under intense pressure from a public dissatisfied with the outcome of the 34-day war, which began when Hezbollah guerrillas captured two Israeli soldiers and killed three others in a July 12 cross-border raid.
