An exasperated RJD President Lalu Prasad today dubbed his former close aide Ramkripal Yadav as demon 'Bhasmasura' for joining BJP after 'setting fire to ideology'.

"I created him (Ramkripal), but he has proved to be 'Bhasmasura'. Lord Shiva was happy and granted a boon to Bhasmasura. But he became a cause of concern for all and nature ensured that he burned. God is removing all such elements from my party," Lalu said today.

He also called Yadav his erstwhile man Friday and Secretary General of RJD, an 'opportunist' for whom Gujarat Chief Minister and BJP prime ministerial candidate Narendra Modi overnight became a 'bhai' (brother).

"He has forgone all his beliefs and burnt ideology to join communal forces. Secular people, minority communities and all others have recognised how he has sold his principles," Lalu alleged. The RJD supremo said he was not responsible for Ramkripal Yadav leaving the party.
