"We need a radical project if we are, all together, to drag ourselves out of the swamp," Matteo Renzi told the Partito Democratico (PD) executive today. "We cannot go forward in a situation of uncertainty." That uncertainty may be at an end. Today Premier Enrico Letta, the sober economist who has managed to placate the EU by bolstering Italy's debt position, seemed on the threshold of being obliged to pass the hand to the slightly younger but more charismatic Renzi, former mayor of Florence. "Mine is zen calm," said Letta, "day to day." Following the conclusion of the PD meeting Letta announced that he would resign formally tomorrow.
