A court in Seoul, South Korea has found the daughter of Korean Air chairman guilty of violating aviation safety law.
Cho Hyun-ah, the daughter of the head of Korean Air, was charged after demanding that a crew member be removed from a flight for failing to serve the nuts on a plate.
It has created worldwide interest, but also sparked a wider debate in Korea over the so-called chaebol system where the economy is dominated by family firms, including Korean Air.
