BJP president Amit Shah on Tuesday asked Opposition parties to take a clear stand on the National Register of Citizens (NRC) issue in Assam and not indulge in vote bank politics, asserting that NRC will be implemented "to the last full stop" as his party stands for national security.

Dismissing criticism by parties like the Congress and TMC, Shah told a press meet that the process for NRC, whose mandate is to identify illegal immigrants, was started in 2005, when the UPA was in power, but the government lacked the courage "to throw out illegal Bangladeshis".
