North Korea President
In short
Kim Jong Un is the supreme leader of North Korea. He recently appeared in state media to dismiss rumours regarding his health following unverified claims of a brain haemorrhage.
In plain words
He is the most powerful person in North Korea. He makes the big decisions for the country and its military. Recently, he has been seen in public to show he is still healthy and in charge.
A simple example
When rumours spread that he had died, he appeared on television to prove he was alive and well.
Why it matters
His health and actions directly affect global security and tensions with South Korea. His leadership determines how North Korea interacts with the rest of the world.
Easy to mix up
Do not confuse him with his sister, Kim Yo Jong, who is a very powerful official but not the supreme leader.
