 According to Jang Jin-sung, Kim Song-ae had the ambition to place her son, Kim Pyong-il in the position of successor to her spouse Kim Il-sung, rather than his son from his first marriage, Kim Jong-il.In this, she was supposedly supported by a faction of the North Korean political elite, among them her brother Kim Kwang-hop, and Kim Il-sung's brother Kim Yong-ju, and opposed by the faction of her stepson Kim Jong-il.In the 1970s, her influence was reportedly seen as excessive by the party, who started to curb it.
