The man who was chosen to lead this attempt did not belong to the leftist wing of the DC, as had happened with the PSI moderation effort, but the moderate leader and former-PM Giulio Andreotti, so as to balance the situation and calm the markets. The first government reliant on support from the communists was thus formed, when the PCI decided to grant its external support. However this process, called "National Solidarity", was dramatically ended by the terrorist attacks of the Red Brigades, which saw the kidnapping and murder of former-PM Aldo Moro. The country was shocked by these killings, and the Communists returned to full opposition. Giulio Andreotti's subsequent attempt to form a classic centre-left government with the Socialists failed, and a new general election was called for 1979.
