Describing the passage of the Citizenship (Amendment) Bill, 2016, in the Lok Sabha as "unfortunate", Meghalaya Chief Minister Conrad Sangma today said he will discuss with his National People's Party (NPP) leaders to take a call on whether to snap ties with the BJP. The Lok Sabha on Tuesday passed the Citizenship Bill that seeks to remove hurdles in eligible migrants from six minority groups from Bangladesh, Pakistan and Afghanistan from getting Indian citizenship despite opposition by political parties.
