Israeli foreign minister woos Shas party which opposes talks with Palestinians on Jerusalem.
Olmert must now submit his resignation to Shimon Peres, Israel’s president, who will grant Livni six weeks to form a new government.
“It has certainly been a very long goodbye … but Olmert could be hanging around for a few months yet,” David Chater, Al Jazeera’s correspondent in Jerusalem, said.
“It is not a surprise that he has announced his resignation at this cabinet meeting – what we need to know now is when he is going to hand his letter of resignation in to Peres.”

After her win in the Kadima party leadership vote, Livni now has the task of forming a coalition government in order to prevent snap general elections.
Polls have indicated that such a vote would sweep the opposition Likud party to power.
Olmert is expected to stay on as a caretaker prime minister until a new government is sworn in.
Should Livni succeeds in forming a coalition, she would become the first female prime minister in Israel for 30 years.
Olmert was hit criticised for his handling of the 2006 war in Lebanon against Hezbollah, which ended without a decisive Isrsaeli blow against the Shia Muslim organisation.
He is also facing several allegations of corruption, with police investigating claims that he accepted cash payments from an American businessman before he became prime minister.
Olmert had said on July 30 that he would step down once a new leader was chosen by the Kadima party.
His resignation comes amid flagging peace talks between Israel and the Palestinians, which by the end of this year were intended to lead towards an agreement on the formation of a Palestinian state.
Although Livni has led the negotiations on the Israeli side, the two sides remain divided over final borders, Jewish settlements in the West Bank, the future status of Jerusalem and the fate of about 4.6 million Palestinian refugees.
Complicating Livni’s attempt to form a coalition, the ultra-Orthodox Shas party has said it will quit the government if the division of Jerusalem between Israel and the Palestinians is broached.
The Palestinians want mostly Arab east Jerusalem, which Israel seized in the 1967 Arab-Israeli war, as the capital of their future state.
