Wang Baoan, former head of the National Bureau of Statistics, has expelled from the Communist Party of China and removed from public office, the country's top anti-graft watchdog said on Friday.

Wang, 53, was vice-minister of finance before he was appointed as head of the bureau in April 2015, according to the Central Commission for Discipline Inspection.

He was put under investigation for "serious violations of discipline" by the CCDI in January.
