Battle over early elections grips Italy in limbo

A fight over whether to hold early elections gripped Italy Tuesday after Prime Minister Matteo Renzi's resignation left the eurozone's third largest economy in political limbo.

Renzi's exit Monday after a crushing referendum defeat over constitutional reforms unleashed the political hounds, with all parties vying to take advantage of the power vacuum.

"Italy is now entering into troubled waters," Giovanni Orsina, political science professor at the Luiss University in Rome, told AFP.

Across the political spectrum, parties were plotting the next move in a high-stakes game with the country's top job as prize.

Renzi, 41, has been asked by the president to stay on for a few days to pass the 2017 budget in a bid to reassure Europe and the markets that the heavily debt-laden country is not the eurozone's next nightmare.

The government has already won a vote of confidence on the budget in the lower house of parliament, but needs the senate's nod.

After that, President Sergio Mattarella will consult with party leaders before naming a new prime minister, though whoever it is will have to have the backing of Renzi's centre-left Democratic Party (PD).

The crisis could see the 2018 elections brought forward by a year and potentially see the populist Five Star movement -- which wants to quit the euro -- seize power.

- 'Too many unknowns' -

Italy's mainstream parties on the left and right share a common interest in keeping the Five Stars out, but disagree on how to do it.

The issue is complicated by the fact that a recent reform to the electoral law only applies to the lower house of parliament now that the constitutional reform bid has failed.

As a result an election now would create different majorities in the upper and lower house, scuppering any possible government.

"There are many forces in play, pulling in different directions," Orsina said.

Renzi wants elections as soon as possible to prevent potential competitors from growing stronger, while the Five Stars and the anti-immigrant Northern League party are also keen to vote early and capitalise on the "No" vote momentum, he said.

But parts of Renzi's PD, Silvio Berlusconi's centre-right Forza Italia party and centrists are against a vote for fear of losing, he added.

"What we'll have now is a compromise with an ambiguous government which at the start will present itself as a simple bridge government to take the country to elections in three or four months, but which could strengthen over time," he said.

The Five Stars said the Italians had "expressed a clear political signal" that they want elections as soon as possible, and founder Beppe Grillo said the party would begin forming a policy platform and a cabinet team next week.

Northern League leader Matteo Salvini also urged an early ballot, saying "real change happens only through electoral victory".

But editorialist Massimo Franco for the Corriere della Sera daily said "no-one is ready to bet on the date of the election," warning there were "too many unknowns" at play for Italians to be rushed back to the polls.

Renzi is expected to seek the support of the PD to remain party leader, a role that would give him a say on who replaces him.

Economy Minister Pier Carlo Padoan is widely tipped for the PM post, as is senate speaker and ex-mafia hunter Pietro Grasso.

Whoever is chosen will become the fourth successive head of government to be appointed rather than elected.
