Young centre-left leader Matteo Renzi was set to be nominated as Italy’s youngest prime minister this weekend after a party coup forced Enrico Letta to resign as premier of the eurozone state struggling to pull out of recession.

Letta bowed out on Friday after the leadership of his Democratic Party (PD) forced him to step aside and make way for Renzi, 39, who is promising bold economic reforms and a government than can survive until 2018.

President Giorgio Napolitano yesterday expected to complete a round of consultations with parties in the evening and could summon Renzi, the PD secretary and current mayor of Florence, soon afterwards to form a government, sources in the party said.

After receiving a mandate from the President, Renzi will have to strike an accord with the small New Centre Right party, whose support the PD needs to command a majority in the Parliament of the eurozone’s third-largest economy.

The party, which split from scandal-plagued tycoon and ex-premier Silvio Berlusconi last year, has ruled out liberal social policies that Renzi has advocated, including gay civil unions, and wants a clear centre-right stamp on the government.

Renzi, whose PD is the largest party in Parliament, would become the youngest leader in Italy’s 163-year history as a united country, younger even – by two months – than Fascist dictator Benito Mussolini was when he took over in 1922.

But before Renzi can stake his claim on history and attempt to install Italy’s 65th government since World War II, he must overcome institutional rituals and much wheeling-and-dealing, a process likely to take several days.

The anti-establishment 5-Star Movement and the pro-devolution Northern League, both Opposition groups, have abandoned the talks, saying they are an empty ritual whose outcome is already written.

But Berlusconi, the centre-right leader who was booted out of Parliament last year after a conviction for tax fraud, accompanied leaders of his Forza Italia party to meet the head of state in the afternoon.

After striking a deal with parliamentary allies, Renzi must name the members of his Cabinet, swear them in, and then seek confidence votes in both Houses of Parliament.

He would become the third prime minister in a row nominated by Napolitano without having won an election. Letta was chosen to helm a right-left government after last year’s deadlocked election, and Mario Monti took over for Berlusconi during a burgeoning eurozone debt crisis in 2011.

“If they think that this is democracy, we don’t agree,” said Vito Crimi, a leading member of the anti-establishment 5-Star Movement in the Senate.

Financial markets have seemed indifferent to Italy’s latest political ruction and investor confidence in the country’s ability pay off its debt is much improved from 2011.

On Friday, Moody’s Investors Service lifted the country’s sovereign rating outlook to stable from negative, after having slashed it by six notches to Baa2 from Aa2 during the debt crisis. But that will not make the challenges facing Italy’s next government any less significant.

Gross domestic product has shrivelled by about seven per cent in the last five years and industrial output has fallen by 25 per cent.

Italy’s economy grew by a measly 0.1 per cent in the fourth quarter of last year, data showed on Friday. It entered its worst post-war recession in mid-2011.

Hundreds of thousands of companies have gone out of business and joblessness has not reached such a high level since the 1970s.

Italy’s €2 trillion of public debt are equivalent to more than 130 per cent of total economic output.
