Following the Ministry of External Affairs' clarification on passport not being proof of citizenship, Opposition leaders took a swipe at the Centre.
Rajya Sabha MP Kapil Sibal asked which document would prove citizenship, while Trinamool Congress MP Mahua Moitra quipped that the only proof of Indian citizenship today is to be both Hindu and a BJP voter.
Shiv Sena (UBT) MP Aaditya Thackeray questioned the verification before passport issuance and whether the document is issued to non-Indians.
The MEA clarified that the passport is a travel document, while highlighting measures incorporated into new chip-based e-passports, such as biometric data, to boost global acceptance and reduce the risk of fraud.
