The top political adviser in Guizhou province has been suspended from his position and is being investigated for an alleged serious breach of party discipline, state media said yesterday. Huang Yao, chairman of the Guizhou Provincial People's Political Consultative Conference, allegedly violated party discipline - a common euphemism for corruption - according to Xinhua. The inquiry had been confirmed by the Central Commission for Discipline Inspection under the Chinese Communist Party, Xinhua said, giving no further details. The news came after the downfall of Song Yong, vice-chairman of the Liaoning provincial people's congress, and Li Tangtang , the vice-chairman of the Ningxia Hui Autonomous Region. Huang is the third provincial-level official brought down - at least temporarily - by the party watchdog in the aftermath of last month's fourth plenum of the 17th Central Committee of the party, which focused on fighting corruption. Huang is also the second regional head of the political consultative body to face such an investigation after the downfall of Chen Shaoji, the former chairman of the Guangdong Provincial People's Political Consultative Conference, who was fired for bribe-taking and a degenerate lifestyle in mid-April. A member of the Buyi minority, Huang has worked in the southwestern province for the past three decades. The 61-year-old reportedly attended a meeting on October 19 with standing members of the Communist Party's Guizhou Provincial Committee to hear comments conveyed from Vice-Premier Li Keqiang , who had just wrapped up a visit to the province. That was Huang's last public appearance before his detention. Huang's abrupt suspension gave rise to wild speculation among mainland internet users that he might be involved in corruption. Meanwhile, Yu Weiliang, the party chief of Longgang district in Shenzhen, was formally sacked for violating party discipline during another gathering of all cadres in the district on Saturday, the Shenzhen Economic Daily reported. Yu's vacancy was filled by Jiang Zunyu , announced Wang Suiming , the head of the party's Organisation Department in Shenzhen, who presided over the meeting. Wang gave no details about Yu's alleged offences. As a Guangdong native who joined the party in 1980, Yu served several government departments in the city before being promoted to lead Longgang district in April 2007. During his tenure, more than 270 billion yuan (HK$306 billion) was spent preparing for the Universiade, an international sports event for university athletes, including the construction of the key venue, due to open in 2011. Yu's removal has not been linked to the huge construction fund, but the Beijing-friendly Wen Wei Po newspaper has reported that corruption on the project contributed to the downfall of Xu Zongheng , the former Shenzhen mayor, in June. In an unusual comment, Li Yuanchao, minister of the party's Central Organisation Department, last week warned cadres at all levels to fight against lustful temptations and other desires, and to keep away from vulgar businesses. Hong Kong-based political commentator Johnny Lau Yui-siu said a series of crackdowns on corrupt officials showed that the central government had resolved to curb worsening corruption. The government was also using the anti-corruption focus to weed out politically defiant officials, he said, to create space for those who follow its policies, ahead of the power reshuffle at the 18th Party Congress in 2012.
