Bengal Chief Minister Mamata Banerjee, who has triggerd a huge "outsider versus insider" debate in the state ahead of the assembly election, today offered a clarification, saying there is no discrimination in the state between Bengalis and non-Bengalis while reiterating her stand on the controversial law on the National Register of Citizens.
