Two former lawmakers of China's Hong Kong Special Administrative Region (HKSAR) pleaded guilty on Tuesday to charges related to an illegal assembly in August 2019, while seven others, including media mogul Jimmy Lai, pleaded not guilty.

Au Nok-hin, a former lawmaker, pleaded guilty to organizing and knowingly taking part in an unauthorized assembly, while Leung Yiu-chung, another former lawmaker, pleaded guilty to participating in an illegal assembly. They were both released on bail.

Lai and eight others charged with organizing and joining an unauthorized assembly appeared in a court in HKSAR on Tuesday.

The trial is expected to last 10 days.
