But a South Korean government spokesman, Jeong Joon-hee, said at a news conference that the diplomat had arrived recently in South Korea with his wife and family, proclaiming disillusionment with the increasingly isolated government of the North Korean leader, Kim Jong-un. So it was a shock on Wednesday when South Korea announced that Mr. Thae had betrayed his hermetic homeland by becoming the most senior North Korean official to defect in nearly two decades.
– A North Korean diplomat stationed in London vanished in mid-July, and Seoul is now explaining why: Thae Yong Ho has defected to South Korea, in what the BBC reports could be the "highest-ranking" defection North Korea has experienced. The New York Times calls Thae the "No. 2" official of the five stationed at North Korea's London embassy, and the Guardian reports it is the first such defection to have occurred since the embassy opened its doors 13 years ago. Thae and his family "are currently under government protection and relevant institutions are going ahead with necessary procedures as usual," said a South Korean unification ministry rep. The Guardian calls the defection a "coup" for global intelligence agencies, who may be able to gain insight into Kim Jong Un's regime. In London, Pyongyang had charged Thae with keeping tabs on defectors living there, and was also supposed to combat negative perceptions of the North.
