TMC MP Derek O'Brien was suspended from the Rajya Sabha for the remaining part of the Winter Session after he allegedly threw the rule book towards the chair on Tuesday.
The linking of Aadhaar and voter ID cards will be "voluntary and not compulsory", Law Minister Kiren Rijiju told NDTV Tuesday, amid protests against the controversial Election Laws (Amendment) Bill and the manner in which it was passed.
Centre on Tuesday said the move would solve the "major problem" of multiple enrolment of the same person at different places and help in "cleaning" the voters list to a great extent.
The bill seeks to allow electoral registration officers seek the Aadhaar number of people who want to register as voters "for the purpose of establishing the identity".
