The botched right-wing coup took place after the Hot Autumn of left-wing protests in Italy and the Piazza Fontana bombing in December 1969 . The failed coup involved hundreds of neo-fascist militants from Stefano Delle Chiaie 's National Vanguard , helped by 187 members of the Corpo Forestale dello Stato , who were to seize the headquarters of the Italian public television broadcaster RAI . The plan included the kidnapping of the Italian President Giuseppe Saragat ; the murder of the head of the police Angelo Vicari ; and the occupation of RAI , the Quirinale , the Ministry of the Interior ( from which Vanguard militants would seize weapons ) , and the Ministry of Defense . Milan-based army dissidents in the Battalion of Lt. Colonel Amos Spiazzi also planned to occupy Sesto San Giovanni , at that time a workers ' town and a stronghold of the Italian Communist Party . Apparently some militants briefly entered the Ministry of the Interior , but Borghese suspended the coup a few hours before its final phase . A gun not returned by one of the militants was later viewed as a key piece of evidence in the sedition trial
