New Delhi: In a big boost to the Narendra Modi-powered BJP, two exit polls on Tuesday predicted that the saffron party will win big in the northeastern state of Tripura. According to the exit polls, the BJP will comfortably dethrone the Manik Sarkar-led Left Front government from power, ending 25-years of its rule in the state. Further, the BJP is also expected to consolidate its position in two other northeastern states - Meghalaya and Nagaland – which too went to polls recently, the exit polls suggested.
