(ANSA) - Rome, August 2 - Deputy Premier Luigi Di Maio on Friday slammed results of an expert report released Thursday evaluating Genoa's Morandi Bridge following its collapse last August, which killed 43 people, and called for a procedure to revoke the contract of motorways concessioner Autostrade per l'Italia (ASPI) "as soon as possible". Di Maio cited in particular the report's findings of "a lack of major maintenance work for 25 years, practically since the State handed over control", calling it unacceptable.
