As senior BJP leader LK Advani set out on his Jan Chetna Yatra from Bihar, RJD supremo Lalu Prasad hit out at Chief Minister Nitish Kumar, accusing him of betraying socialist leader Jayaprakash Narayan. Mr Kumar flagged off Mr Advani's yatra from Sitabdiara in Chhapra, the birthplace of Jayaprakash Narayan, whose anti-corruption movement in the 70s changed Indian politics.
