TOKYO (AFP) -- The eldest son of North Korea's late leader Kim Jong-il has secretly visited Pyongyang to pay his last respects, the major Japanese daily Yomiuri Shimbun reported Sunday.
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.
Jong-nam, 40, flew to Pyongyang from the Chinese territory of Macau, where he mainly lives, on Dec. 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.
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 Dec. 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 Jong-nam "pulled out of the succession race several years ago by himself, saying he had no interest in politics," according to Yomiuri.
