ROME (Reuters) - The Italian government was left red-faced on Tuesday when a third health chief in Calabria quit in barely a week, leaving the southern region’s hospitals rudderless and still lacking an emergency coronavirus plan.The resignation of any senior state bureaucrat is unusual in Italy, where officials tend to cling to their jobs until retirement, but to see three throw in the towel in such swift succession is remarkably rare, if not unprecedented. The rapid departures also raised questions about government oversight of one of Italy’s poorest regions, which has been designated a coronavirus “red zone” partly because its hospitals are believed to be incapable of handling a major outbreak. The latest governor, Eugenio Gaudio, resigned less than 24 hours after the cabinet had appointed him. Gaudio, who previously headed Rome’s Sapienza University, said he had decided not to take the job because his wife did not want to move to Calabria. “I have no intention of starting a family crisis,” said Gaudio, whose candidacy had caused mutterings of discontent in Italy’s ruling coalition after it emerged that he was under investigation for alleged irregularities in university hirings.
