RJD chief Lalu Prasad Tuesday compared BJP's prime ministerial candidate Narendra Modi to a butcher, without naming him."Wo humse kya ladenge jinhe dekh kar kasai bhi sharmata ho (How will they fight us when even a butcher is ashamed on seeing them)," the Rashtriya Janata Dal (RJD) chief said in a tweet.He added he is a "son of the soil".The remark comes after Trinamool Congress leader Derek O'Brien Sunday, in a tweet, called Modi the "butcher of Gujarat".Asked about the jibe, BJP spokesperson Ravi Shankar Prasad said the remark was made as the defeat is staring in the RJD's face."What should I say on this? Maybe he can see defeat is looming," Prasad said.
