Instead, it asked the Central Government to create a national citizen register and issue multi-purpose cards to all citizens to fulfill security concerns.

"We can understand the Lt Governor's intention. But in reality 50 per cent of the people in Delhi does not possess any kind of identity card," BJP spokesperson Prakash Javadekar said.

He said the BJP had been demanding creation of a national citizen register and issuance of multi-purpose smart cards, which is handy and water-proof.

"In the present situation, the suggestion seems to be impractical," he said.

Javadekar said it is to be seen whether Delhi Lt Governor's Tejinder Khanna's suggestion fulfills the basic aim of addressing security concerns or is reduced to just checking of citizens.
