Parliament on Monday approved the controversial bill providing 27 per cent reservation for Other Backward Classes in Centrally-aided educational institutions with the Rajya Sabha passing the measure by a voice vote.

The House went in for a division on an amendment moved by Bharatiya Janata Party, which was defeated by 91 votes against and 24 in favour.

Replying to the marathon debate on the Central Educational Institutions (Reservation in Admission) Bill, 2006, Human Resource Development Minister Arjun Singh [Images] said that a separate bill on providing reservations for OBCs in unaided institutions was ready and will be brought before Parliament later.
