China's top graft-buster launched a scathing attack on the ruling Communist Party's members on Monday, writing that party political culture remained "unhealthy" and governance weak even after five years of renewed effort to fight the problem. The comments by Wang Qishan, who runs the party's anti-corruption watchdog, came after sources said a senior official who was considered a contender for promotion at autumn's key party congress is being investigated for "discipline violations".
