Campaigning in Meghalaya, Tripura and Nagaland will heat up, now that the assembly election dates have been announced. In December, Prime Minister Narendra Modi visited Meghalaya and Mizoram in what was seen as the launch of the Bharatiya Janata Party's campaign for assembly elections in the north-east this year. BJP president Amit Shah also went to the north-east last week to prepare the party for the fight ahead.
