Chinese authorities have formally charged former domestic security chief Zhou Yongkang with bribery, abuse of power and intentional disclosure of state secrets, state media said on Friday, paving the way for a trial that underscores Beijing's commitment to fighting graft at the highest levels.
Zhou, 72, is by far the highest-profile figure caught up in President Xi Jinping's crackdown on corruption. He is the most senior Chinese official to be ensnared in a graft scandal since the party swept to power in 1949.
Zhou was a member of the Politburo Standing Committee - China's apex of power - and held the post of security tsar until he retired in 2012.
His case was transferred to a court in the northern city of Tianjin on Friday, state news agency Xinhua said.
No date was given for Zhou's trial, but state media said last month that China would hold an "open trial" in an attempt to show transparency.
Last year, China said it had arrested Zhou and expelled him from the ruling Communist Party, accusing him of crimes ranging from accepting bribes to leaking state secrets. It also said his case had been handed over to judicial authorities.
Retired legislators and lawyers have said many of the previous abuses to the rule of law in China can be attributed to Zhou, who expanded his role into one of the most powerful and controversial fiefdoms in the one-party government.
