According to a news report, Lalu's anger towards Modi came after a poll survey predicted that his party will bag only three seats in Bihar.
Trashing away the poll survey findings, Lalu confidently asserted that his party will win all 40 parliamentary seats.
Claiming that BJP is spreading false propoganda in the name of "Modi wave", RJD Chief said that it is only a media creation and the balloon will bust on May 16, when the election results will be declared.
In an interview to ET, Lalu claimed that he has already punctured Modi's balloon and BJP exists only in media and news channels.
Earlier, Lau had said Varanasi would prove to be a "political graveyard" for Modi.
He also described Bihar Chief Minister and JD(U) Chief Nitish Kumar and Modi as "bosom friends" fighting in public to "befool" voters.
