Zhou Yongkang: China investigates ex-security chief

China's former security chief Zhou Yongkang is being investigated for suspected "serious disciplinary violation", state media say.

Mr Zhou headed China's Ministry of Public Security and was a member of the top decision-making body, the Politburo Standing Committee.

Damian Grammaticus in Beijing says the investigation sends a "significant" political and public message over corruption and President Xi Jinping's authority.
