"All the 44 deaths that are being linked to Vyapam scam has nothing to do with it," the Lok Sabha MP from Jabalpur told a press conference here.
Singh, also party affairs in-charge for Maharashtra, said that it was MP chief minister who first initiated a probe into the scam.
Meanwhile, on ministers in the Maharashtra government charged with corruption, Singh said it is the individual who is facing allegations and not the Devendra Fadnavis-led BJP government.
None of the charges have been proved so far, he added.
