Where is Kim Jong Un?

It’s been thirty seven days since North Korean leader Kim Jong Un was last seen in public. Today, he didn’t turn up at the big anniversary ceremonies for the founding of the Workers’ Party. That’s when everyone who’s anyone pays their respects at the palace-turned-mausoleum where the embalmed bodies of his father and grandfather lie under clear glass. So…where is Kim Jung Un? Is he sick? Has he been overthrown? Who’s running the country?
