I want to know the answer to the following question:
Who voted in favor of an official investigation of the accusations?
All the background I'm provided with is that "However, the accuracy of the revised figures has also been questioned, and in February 2012 the Hellenic Parliament voted in favor of an official investigation following accusations by a former member of the Hellenic Statistical Authority that the deficit had been artificially inflated in order to justify harsher austerity measures.". Is that enough to answer the question?
Answer: yes
