Bologna — As of this week, Matteo Renzi is Italy’s third prime minister in a year. He follows Mario Monti (November 2011-April 2013) and Enrico Letta (April 2013-February 2014). At 39, Renzi is absurdly young by Italian standards, where in politics one’s sixties are seen as an apprenticeship period and one’s seventies are the time of full flowering. Renzi is full of reformist plans, as were his predecessors. He has had no national governing experience, but neither did Silvio Berlusconi when he came to the prime minister’s office in 1994.
