Kim Jong-un's wife reappears after two-month absence South Korea's intelligence agency had joined the fray of speculation over the sudden disappearance of Ri from state media since early September saying state elders may have raised an issue over her casual and cheerful demeanour portrayed in media. "The analysis has been that there was concern over breach of discipline (by Ri) among North Korean elders, plus the speculation of pregnancy," South Korea's Chosun Ilbo newspaper quoted the National Intelligence Service as reporting in a closed-door briefing to parliament. North Korea broke the mystery surrounding a young woman who had been seen with Kim in July by saying she was the leader's wife. The announcement itself was part of a trend that Kim has followed to break out of the secretive management style of his father. North Korea's state media have not disclosed when the two got married or whether they had any children.
