China sacks former security chief Zhou Yongkang's associate
Chinese authorities have sacked another associate of Zhou Yongkang, in the latest apparent move targeting the powerful former security chief.
The Communist Party's anti-corruption watchdog said that Guo Yongxiang, a former vice-governor of Sichuan province, had been expelled from the party and removed from office.
