Former Hong Kong chief executive Donald Tsang Yam-kuen was sentenced on Wednesday to 20 months in prison for misconduct in public office, making him the highest-ranking former government official in the Hong Kong Special Administrative Region to be sent to jail.

Tsang was found guilty on Friday of misconduct for failing to declare a conflict of interest when he approved an application for a radio broadcasting license from broadcasting company Wave Media. At that time, he was in negotiations with a businessman, who was a major shareholder of Wave Media, over a rental apartment in Shenzhen, which Tsang intended to use after he retired.

He was acquitted of a second count of misconduct.
