The Communist Party of China's discipline inspection team in Hunan province has announced it is investigating 431 CPC members and government workers on suspicion of electoral fraud in December 2012 and January 2013.

Those suspected of having broken the law will be passed on to judicial authorities, the inspection team said.

The news follows a statement from the provincial legislature on Saturday that more than 500 local lawmakers had been disqualified, dismissed or have resigned over the electoral fraud in Hengyang, the second-largest city in Hunan.
