Prime Minister Narendra Modi used the development issue again today to hit out at Chief Minister Nitish Kumar at the first of his four rallies in Bihar. The BJP's huge campaign push comes ahead of the third phase of the assembly elections in the state. "Nitish Kumar and Lalu Prasad are answerable to the people for forcing people to leave the state. They made migrants of the youths of Bihar," the PM said at the rally in Chapra.
