An MLA of the ruling Bharatiya Janata Party in Assam has been served a notice to prove his citizenship amid the exercise to update the National Register of Citizens (NRC) that is nearing completion. Kishore Nath and six members of his family were served the notice on Friday by the Foreigners’ Tribunal No 1 on suspicion of being doubtful voters. Mr. Nath, 53, represents the Barkhola Assembly seat in southern Assam’s Cachar district.Other members of his family served notice include his wife Nilima Nath and four brothers. “We shouldn’t have received this notice as we have been living here for three generations. I believe some mischief was done during a verification process during 2008-2012 when the Congress ruled,” Mr. Nath said.
