The vote in the Senate came hours after he argued that he could get his country back to work while the last three premiers failed. Renzi, at 39 Italy’s youngest premier, was sworn into office on Saturday along with an unusually young Cabinet, with many of the ministers newcomers to national government.
The Senate voted 169-139 to confirm Renzi’s broad coalition, which ranges from his centre-left Democrats to centre-right forces formerly loyal to ex-premier Silvio Berlusconi.
Renzi needed at least 155 votes to clinch the victory, one of two mandatory confidence votes. The second vote, in the Chamber of Deputies, was expected later on Tuesday.
Renzi’s coalition has a comfortable majority in the lower chamber. But he had a closer call in the Senate, where his coalition’s numbers were tighter, especially after some of his own Democrats questioned on the eve of the vote if he deserved their backing.
There has been loud grumbling among his own Democrats over Renzi’s heavy-handed tactics to wrest the premiership from fellow Democrat Enrico Letta. His predecessor led a coalition with the same tense partners for 10 months, but Renzi engineered his ouster after industrialists and union leaders grew impatient with tentative efforts to energise the economy after years of stagnation. In the end, the potential defectors closed ranks, despite scepticism, after Renzi made a speech that was short on details on how he would quickly revive the economy.
“I don’t believe that a government of this type can last four years,” said Felice Casson, a leading Democrat who said he voted for Renzi “despite indigestion” over the neophyte premier’s leadership.
