The first of such flags will be hoisted on the restive JNU campus, officials in the HRD Ministry said.
"At a central place in every university, the national flag will be flown prominently and proudly," the resolution passed at a meeting Irani had with the Vice Chancellors of Central universities, said.
The move drew a sharp reaction from the Congress which said nationalism doesn't mean hoisting the flag and singing Vande Mataram and that it should be reflected in one's belief in the Constitution. CPM leader Brinda Karat also slammed government for the decision.
The proposal for hoisting the national tricolour atop a 207-feet pole was put forward by Irani and unanimously endorsed by all the 46 Vice Chancellors, HRD officials said. She also put forth the proposal for hoisting the first such flag at JNU, which too was backed by all the VCs, they said.
Irani had called the meeting of VCs following widespread protest over suicide of dalit scholar of Hyderabad University Rohith Vemula.
"Nationalism just doesn't mean hoisting the flag and singing Vande Mataram. It is about showing your belief in the Constitution, it is about showing respect to the institutions which have made the country a democratic set up," Congress' R P N Singh said.
At the meeting several important aspects related to higher education, including the implementation of 2012 UGC regulations by varsities for promoting equity and addressing grievances of Scheduled Caste and Schedule Tribe students discussed.
