NORTH KOREA, a past master of pageantry, has staged a spectacular coming-out ceremony for its leader-in-waiting, Kim Jong Un, while making it clear that his ailing father Kim Jong Il, remains very much in command. The two men reviewed a parade of tanks, missiles and goose-stepping solders which cut through the centre of Pyongyang, providing citizens with a striking demonstration of the Kim dynasty’s power and its plans to keep it in the family.
