Still smarting from the drubbing in three heartland states and facing the greatest challenge from within, the beginning of the election year spells little cheer for the ruling BJP-led NDA. Sixteen of its constituents, both big and small, have quit since Prime Minister Narendra Modi took over in 2014. The latest instance came exactly a week into 2019, when the BJP’s ally in Assam, the Asom Gana Parishad (AGP) led by Prafulla Kumar Mahanta, pulled the plug on the NDA over the passage of the Citizenship (Amendment) Bill 2016, which seeks to grant Indian citizenship to non-Muslims from Bangladesh, Pakistan and Afghanistan.
