A fierce battle is being waged behind the scenes for control of North Korea as Kim Jong-il prepares to anoint his successor, it has emerged.
Factional in-fighting has broken out between Chang Song-taek, the rogue state’s second-in-command, and a group of senior reform-minded officials, according to a source who has recently met people at the highest levels of the North Korea n government.
The battle between the two sides comes as Kim Jong-il, the 68-year-old “Dear Leader”, is in frail health and no concrete succession plan has yet to emerge.
Chang, 64, is married to Kim’s sister and “always believed the crown would be his [one day]”, according to the source. His ambition may yet be fulfilled, since many observers believe he could take charge of North Korea as a regent while Kim’s third son, the 28-year-old Kim Jong-un, gains experience.
