Kim Tu-bong
In his first confrontation with his rivals, Kim Il-sung managed to get the Soviet-Koreans to attack the domestic faction. The majority of cadres belonging to the domestic cadres still felt affinity with the party in Seoul and did not support Kim Il-sung's leadership. Cadres belonging to the Yanan faction did not speak out during the congress; with leading figures such as Kim Tu-bong and Choe Chang-ik remaining silent. O Ki-sop tried to get them involved, accusing Mu Chong of "individual heroism", but Mu Chong did not reply and Kim Il-sung condemned O Ki-sop for dragging Mu Chong into a discussion about himself. However, the fact is that it wasn't much the domestic faction could do to weaken Kim Il-sung's authority since he was supported by the Soviets, making him to a certain extent unremovable. At this congress, Kim Il-sung and his allies purged all those WPNK members who had collaborated with the Japanese in one way or another during the occupation—the majority of those who had belonged to the domestic faction since the other factions were headquartered abroad during the occupation.
