SEOUL: North Korea's leader has taken his daughter to a meeting with missile scientists in her second public appearance, in which state media called her Kim Jong Un's 'most beloved' child, deepening outside debate over whether she is being primed as his successor.

The daughter, believed to Kim's second child named Ju Ae and about 9 or 10 years old, was first unveiled to the outside world last weekend in state media photos showing her observing the North's intercontinental ballistic missile launch the previous day with her parents and other older officials. The daughter wearing a white puffy coat and red shoes was shown walking hand-in-hand with Kim past a huge missile loaded on a launch truck and watching a soaring weapon.
