The official announcement of the investigation of China’s former security chief Zhou Yongkang for suspected "serious disciplinary violation", according to China’s state media, has sent shockwaves throughout China.
Zhou, as a former member of China’s top Politburo Standing Committee, is the most powerful political figure to be investigated in China since the Gang of Four in the early 1980s.
He is also the the biggest win for Chinese president Xi Jinping, who first eyed a crackdown on China’s "tigers" and "flies," meaning both powerful political leaders as well as lowly bureaucrats, during the 18th general meeting of the Central Commission for Discipline Inspection in January 2013.
Since then, 466 officials have been investigated, according to disclosures by the Central Commission for Discipline Inspection. The campaign gained momentum in the second half of 2013, when the number of investigated officials increased from 200% to 400% on a quarter-on-quarter basis.
The number of investigated officials above provincial and ministerial levels also skyrocketed, up to around 20 during the first half of 2014 from five in 2012.
Here, we decipher the campaign in the infographic below.
