ROME — Premier Mario Monti told the Italian president Saturday he is resigning soon, saying he can no longer govern after Silvio Berlusconi's party withdrew crucial support. It paves the way for early elections a year after the unelected economist helped pull the country back from the brink of financial disaster.
Only hours earlier, Berlusconi said he would run for a fourth term as premier, aiming for a dramatic comeback, considering the billionaire media baron quit in disgrace in November 2011.
The office of President Giorgio Napolitano, who met for nearly two hours with Monti at the presidential palace, said the premier told the head of state that without the support of Berlusconi's party, "He cannot further carry out his mandate, and consequently made clear his intention to resign" once Parliament passes a crucial budget bill.
Political turmoil in Italy, mired in recession and trying to escape the eurozone sovereign-debt crisis, could spook financial markets, which, with Monti at the helm, had steadily regained faith in the country's ability to honor its debts.
Standard & Poor's rating agency, indicating Friday that it could lower Italy's rating if the recession endures well into 2013, cited "uncertainty" over whether the next Italian government could stay the tough course of austerity Monti's nonpartisan government moved through Parliament.
Monti is an economist appointed by Napolitano a year ago to head a nonelected government of technocrats that replaced Berlusconi.
The premier told Napolitano he would quickly consult political leaders on prospects for swift passage of the "financial stability" budget law key to soothing market fears.
The presidential-palace statement said Monti warned that if lawmakers didn't unite behind the bill, that would render "ever more grave the consequences of a government crisis, on a European level as well."
With elections ever closer, politicians would be loath to shoulder the blame for fueling the crisis. Both Berlusconi's party, and its rival center-left Democratic Party, would likely quickly approve the budget law in the next few weeks.
Once the budget bill passes, Monti will "hand in his irrevocable resignation in the hands of the president," the presidential palace said.
Monti concluded his government's effectiveness was dwindling after back-to-back blows from Berlusconi's conservative Freedom People, the largest party in Parliament. On Thursday, it refused to back two confidence votes in Parliament that the government had tied to legislation.
Before an election date can be set, Napolitano must dissolve Parliament, whose full term runs until late April. Elections must be held within 70 days of Parliament's dissolution, meaning balloting could be held perhaps as early as February, or weeks ahead of the March 10 date that Berlusconi said would suit him.
Earlier in the day, Berlusconi, 76, said he was "running to win," despite polls that indicate his party's popularity has slumped dramatically, and could pull under 15 percent of the vote.
Besides bowing to the financial-market pressure last year, Berlusconi has suffered other blows.
In October, a Milan court convicted him of tax fraud in connection with dealings in his media empire and sentenced him to four years in prison. He is appealing.
He is on trial in another Milan courtroom for allegedly paying an underage prostitute for sex and using his office as premier to try to cover it up. Both he and the young woman have denied they had sex.
