Is Kim Jong-un ready to lead?

Kim Jong-un, the youngest son of North Korea’s late leader Kim Jong-il, is now expected to inherit power from his late father, who died on Monday from a heart attack.

But little is known about the man, who was educated in Switzerland under a false name, and then at a military academy at home.

As Al Jazeera’s Will Jordan reports, there are questions over whether he is ready to lead.
