Kim Jong-un

After North Korea's controversial rocket launch and celebrations to mark the centenary of the birth of the country's "Great Leader," David Torrance profiles the country's new young leader, Kim Jong-un. Little is known about him in this most secretive of states. But after the death of his father Kim Jong-Il late last year, he has begun to establish his authority in relation to North Korea's military and ruling communist party, and he has been confirmed this week in the most senior political office. He will also have to decide how far to seek rapprochement with the outside world. Has his education, partly in Switzerland, made him a new kind of North Korean leader?
