New Delhi, June 27 (ANI): Delhi University students have started an indefinite hunger strike demanding the resignation of Delhi University (DU) Vice Chancellor (VC) Dinesh Singh and an immediate rollback of the Four Year Undergraduate Programme (FYUP). Dhruv Sangwan, South Campus President from Indian National Students' Organization ( INSO ) said that students were suffering due to the confusion at the time of admission. Meanwhile, many protesting students and teachers have also gathered outside the VC's residence demanding his resignation. The standoff between the University Grants Commission (UGC) and Delhi University has resulted in an inordinate delay in the admission procedure. The Delhi University yesterday proposed that all Honours courses except B.Tech should be reverted back to the three year format.
