Journalist Gao Yu was sentenced to seven years in prison by Beijing's Third Intermediate People's Court after being found guilty in a closed trial of leaking state secrets to foreign media. Ms Gao was accused by the court of leaking an internal Communist Party directive to an overseas Chinese news site in 2013, according to her lawyer, Mo Shaoping. Historically, it is rare for Chinese authorities to detain or jail elderly critics, who were traditionally given quiet warnings when they crossed political red lines.
