A former political adviser found guilty of corruption was posthumously stripped of his membership in the Communist Party of China, state media reported. Song Pingshun, formerly Tianjin's representative to the Chinese People's Political Consultative Conference, was found dead on June 3. Police ruled that he had committed suicide. The party's Central Commission for Discipline Inspection said Song had "abused his public power to seek benefits for his mistress, seriously violating CPC discipline." Xinhua News Agency described the posthumous expulsion as "a rare step" for the party. Song had also served as the city's vice mayor and police chief. A number of other corruption investigations are ongoing in Tianjin.
