Italy was mired in fresh political chaos after the populist parties’ bid to take power collapsed with the president set to appoint Monday a pro-austerity economist to lead a technocrat government ahead of new elections. President Sergio Mattarella vetoed the nomination of fierce eurosceptic Paolo Savona as economy minister, enraging the anti-establishment Five Star Movement and far-right League and prompting their prime minister-elect to step aside. “I have given up my mandate to form the government of change,” said lawyer and political novice Giuseppe Conte, 53, plunging the country into a political crisis nearly three months after March’s inconclusive general election. Mattarella said he had accepted every proposed minister except Savona, who has called the euro a “German cage” and said that Italy needs a plan to leave the single currency “if necessary”. The leaders of Five Star and the League, Luigi Di Maio and Matteo Salvini, denounced the veto, decrying what they called meddling by Germany, ratings agencies and financial lobbies. Mattarella has summoned Carlo Cottarelli, an economist formerly with the International Monetary Fund, for talks Monday, with a temporary technocrat government on the table as Italy faces the strong possibility of new elections in the autumn. Cottarelli, 64, was director of the IMF’s fiscal affairs department from 2008 to 2013 and became known as “Mr. Scissors” for making cuts to public spending in Italy. He will struggle to gain the approval of parliament with Five Star and the League commanding a majority in both houses. “They’ve replaced a government with a majority with one that won’t obtain one,” said Five Star leader Luigi Di Maio to supporters at a rally near Rome. – ‘Diktats’ – A former judge of Italy’s constitutional court, Mattarella has refused to bow to what he saw as “diktats” from the two parties which he considered contrary to the country’s interests. He had watched for weeks as Five Star and the League set about trying to strike an alliance that would give Italy’s hung parliament a majority. Mattarella said that he has done “everything possible” to aid the formation of a government, but that an openly eurosceptic economy minister ran against the parties’ joint promise to simply “change Europe for the better from an Italian point of view”. “I asked for the (economy) ministry an authoritative person from the parliamentary majority who is consistent with the government programme… who isn’t seen as a supporter of a line that could probably, or even inevitably, provoke Italy’s exit from the euro,” Mattarella said. The president said Conte refused to support “any other solution” and then, faced with Mattarella’s refusal to approve the choice of Savona, gave up his mandate to be prime minister. The leaders of Five Star and the League, Luigi Di Maio and Matteo Salvini, were infuriated by Mattarella’s refusal to accept Savona, a respected financier and economist. Salvini, who was Savona’s biggest advocate and a fellow eurosceptic, said on Sunday that Italy wasn’t a “colony”, and that “we won’t have Germany tell us what to do”. “Why don’t we just say that in this country it’s pointless that we vote, as the ratings agencies, financial lobbies decide the governments,” a livid Di Maio said in a video on Facebook. Later on Italian television he called for impeaching Mattarella. “I hope that we can give the floor to Italians as soon as possible, but first we need to clear things up. First the impeachment of Mattarella… then to the polls,” Di Maio said.
