Factions
The PNI, the largest of the PDI's five parties, and the legatee of Sukarno, had its base in East and Central Java. IPKI had been strongly anti-PKI in the Old Order in contrast to the once-leftist Partai Murba. Even more heterogeneous than the United Development Party (PPP), the PDI, with no common ideological link other than the commitment to the Pancasila as its sole principle, was faction-ridden and riven with personality disputes.
This factionalism was displayed in the 1977 Legislative Elections, the first Legislative Elections that PDI participated in. The Party was unable to show a united front and would come third and last in the 1977 Legislative Elections.
