The BJP is set to end the two-decade run of the CPM's Manik Sarkar as Tripura Chief Minister. The party and its new regional partner Nationalist Democratic Progressive Party have also pulled ahead in Nagaland and will form government if they hold on to current leads. In Meghalaya, the ruling Congress is leading but could fall short of a majority and is scrambling to try and ensure that the BJP does not manage to gather regional allies for a post-poll alliance to form government.
