Two senior officials in Shanxi province are being investigated for suspected grave violations of discipline and the law - a euphemism for corruption - the country's top anti-graft organization said on Thursday.

Both Ling Zhengce, vice-chairman of the Shanxi provincial political advisory body, and Du Shanxue, a vice-governor, are provincial-level officials.

The Communist Party of China Central Commission for Discipline Inspection released the news on its website, but stopped short of giving more details about the investigation.
