Kim Jong-nam has died in Malaysia
Kim Jong-nam, 45, was the oldest son of Kim Jong-ill, Kim's father and predeccesor.
Initial reports by South Korean media say he was poisoned at Kuala Lumpar airport by two women said to be North Korean operatives.
Kim-Jong-nam had spent the best part of a decade in exile, having fallen out of favour with his late father.
He had been favourite to replace Kim Jong-il as leader until he was arrested at a Tokyo airport in 2001 with a forged passport.
The incident caused great embarresment to the leader, and Nam was exiled to China, where he lived in Macau on the south coast.
Malaysian police told Reuters an unidentified North Korean man died en route to hospital from a Kuala Lumpur airport.
The police said the man's identity had not been verified.
