Xu Zhiyong, a prominent human rights lawyer who campaigned against corruption, has gone on trial in China.
Mr Xu is charged with "gathering crowds to disrupt public order". He is one of several activists from a transparency movement to be tried this week.
Rights groups have criticised President Xi Jinping, who pledged to fight corruption, over their trials.
