A Bharatiya Janata Party legislator criticised West Bengal Chief Minister Mamata Banerjee over her stand on the National Register of Citizens exercise in Assam. Surendra Singh accused the All India Trinamool Congress chief of playing politics with the aid of foreign powers. He said Banerjee can become a politician in Bangladesh if she wants to do politics for Bangladeshis. He also said that the TMC chief can be 'taught a lesson' like Congress leader P. Chidambaram.
