ROME (AP) -- The Italian government's chances of survival rose on Monday as some of former Premier Silvio Berlusconi's longtime loyalists vowed they would not support his attempt to bring down the fragile coalition.
Berlusconi demanded last weekend that the five ministers from his political party quit Premier Enrico Letta's government. He asked them to resign in a show of solidarity ahead of a Senate vote to strip him of his seat because of his tax-fraud conviction.
The ministers, some of them reluctantly, bowed to Berlusconi's demand, plunging the country into political uncertainty. Letta called a confidence vote in Parliament for Wednesday to determine the five-month-old administration's future.
The prospect of the government collapsing worried investors, who sold off the country's stocks and bonds early Monday. There are fears the country would suffer weeks or months of political uncertainty that could derail its attempts to get the economy back on track. Memories are still fresh of this year's inconclusive elections, which left politicians squabbling for two months before Letta's unusual left-right coalition was cobbled together in April.
Letta wants to press ahead with reforms needed to bring the economy, the eurozone's third-largest, out of recession and reduce public debt, which is forecast to near 130 percent of GDP this year.
An unstable Italian economy could, some argued, revive the European financial crisis, which had lain dormant for months.
But such fears eased somewhat as a split emerged in Berlusconi's party over whether to pull the plug on the government.
At least four of the ministers who quit have said they are considering giving their support to Letta in Parliament. There were also signs of a challenge to Berlusconi's leadership from his political heir, Interior Minister Angelino Alfano. Alfano was reportedly worried about the political repercussions -- for himself and the Freedom People party -- of bringing down the government in the middle of a recession for no better reason than to defend Berlusconi in his personal judicial woes.
Dissent among Berlusconi's aides also was fueled by a decision by many senators in Berlusconi's party to quit in protest if a Senate committee later this week votes to strip him of his seat because of his conviction.
"I have expressed strong opposition to our lawmakers' decision to resign," said just-resigned Reforms Minister Gaetano Quagliariello, a longtime Berlusconi stalwart who appeared to be shaping up to be the leader of an influential, disenchanted faction in the media mogul's leadership ranks.
In an interview with one of Berlusconi's networks, Quagliariello urged his center-right colleagues to avoid "the risk of a crisis that would explode for the country and not be understood by our electorate." He said it would be "folly" if his own party brings down Letta's government.
A late-day strategy huddle with Berlusconi and his key lawmakers only yielded confused signals and no immediate way out of the political crisis, said Fabrizio Cicchitto, a former parliamentary whip who has blasted the conservative leader's strategy to make the ministers quit and provoke the parliamentary showdown.
"I asked for a debate, but (the request) was politely blown off," Chicchitto said after emerging from the hours-long meeting.
Participants said Berlusconi did all the talking and quoted him as offering to back Letta for "seven days," in other words, just enough limited support to pass the stability bill, as well as reverse a sales-tax hike and abolish a property tax, both promises to his electorate.
But Cicchitto indicated that Berlusconi's hardliner tactics had essentially left him with no room to maneuver.
"Either we freeze the ministers' resignations, and in doing so, eliminate the reasons for a confidence vote, or (Berlusconi's) party must vote in favor" of Letta in order to keep the government afloat, so the tax relief can be passed, Cicchitto said.
Further easing concerns about a government collapse, a top leader in Letta's center-left Democratic Party said the government might avoid a make-or-break confidence vote. Instead, it might seek Parliament's approval on specific motions, likely tied to key economic measures and electoral reform that could serve to calm jittery markets.
"It's very likely that what will happen is that individual motions will be voted on" in confidence votes not formally tied to the government' survival, said Dario Franceschini, minister of parliamentary relations.
Should Letta's government fall, the president has said he will make dissolving Parliament his last resort. That means several weeks could go by while the president sees if another coalition can be cobbled together, possibly with moderates defecting from Berlusconi's ranks. That should earn the government enough time to pass a key budget law by mid-October. The law is needed to bring the deficit back within EU limits and avoid sanctions by the European Union.
