Kim Jong-il's eldest son in secret visit to North Korea Kim Jong-nam's absence from a state funeral and other official events related to his father's death has fuelled speculation about a possible power struggle with his half-brother Jong-Un, who has taken over North Korea's top posts. Kim Jong-nam, 40, flew to Pyongyang from the Chinese territory of Macau, where he mainly lives, on December 17 after learning about his father's death that day, Yomiuri said. He left after "a few days" and was now in Macau, the report said. Using a passport under the false identify of Kim Chol, he avoided a flight via Beijing which might have given more exposure to his return home, the daily said quoting a source connected to North Korea. Kim Jong-un, aged in his late 20s, was presumed to have accompanied his older brother to see their father's body, Yomiuri said. The eldest son probably refrained from attending the December 28 funeral because he did not want to give rise to possible arguments over "why the third should become the successor," the source told the daily. The source added that Kim Jong-nam "pulled out of the succession race several years ago by himself, saying he had no interest in politics," according to Yomiuri. Kim Jong-nam has lived abroad for years after apparently falling out of favour with his father for trying to enter Japan on a false passport in 2001. Kim Jong-il eventually backed his youngest son from another marriage to continue the dynasty. The North has proclaimed Kim Jong-un the "great successor" and the supreme commander of the military after his father's death due to a heart attack aged 69. South Korea's Yonhap news agency reported last week that Kim Jong-nam had been "placed under Chinese protection." Kim Jong-nam has described as a "farce" South Korean media reports in 2009 that people around Kim Jong-un had tried to assassinate him in Macau, the source told the daily.
