Calling for a change in regime in Bihar, RJD chief Lalu Prasad Yadav said, "Roti should be flipped on the 'tawa' otherwise it would burn...20 years is too long!" "Now, a Tejashwi government is necessary for making a new Bihar," he added. Tejashwi is Mahagathbandhan's CM candidate. Lalu and his wife Rabri Devi cast their vote in Patna today.
