Union Minister for Human Resource Development Prakash Javadekar has announced a 25 per cent increase in seats across educational institutions to ensure that the 10 per cent reservation recently given to the Economically Backward Section (EWS) does not disturb existing quotas for the sheduled castes, scheduled tribes and other backward classes. The changes will be carried out from the 2019-2020 academic session, he told reporters at a press meet held in the national capital today.
