The eldest son of the recently deceased dictator Kim Jong Il thinks that the North Korean regime will soon collapse, according to a book to be published this week.
Kim Jong Nam, who was once thought to be his father's preferred successor as leader of the communist state, also criticises the rule of his half-brother, Kim Jong Un, calling him a "nominal figure".
The book, which will be eagerly scrutinised by North Korea watchers starved of reliable information about the regime's inner circle in Pyongyang, is written by a Japanese journalist Yoji Gomi who says he carried out a lengthy email exchange with Kim Jong Nam over a period of several years. Its publication comes just a month after the death of Kim Jong Il, who had ruled the secretive country since 1994.
Kim Jong Nam spends most of his time in Macau after being banished from North Korea following an incident in 2001, when he was caught trying to enter Japan on a fake passport, allegedly to visit Disneyland.
In the forthcoming book, Kim Jong Nam says it is common practice for high-ranking North Koreans to travel using fake identities, and he also asserts that new leader Kim Jong Un has visited Japan on a forged Brazilian passport.
