"Jameen par aay gaye (now he has come on ground)," Yadav said while referring to Modi's allegation that the EC had failed to check "rigging and violence" in West Bengal, Bihar and western Uttar Pradesh.
"When people get the sense of defeat they start talking about irregularities in the game," he told reporters here.
Lauding EC for conducting free and fair polls for which it has drawn appreciation from across the world, he said those challenging EC were in fact "innocent" and "out to destroy its credibility".
"Even my vehicle were checked and two cases of poll code violation filed against me, but I never pointed fingers on EC," he said.
