The Congress-backed National Students Union of India (NSUI) on Saturday won all four seats in the Delhi University Students Union (DUSU), officials said.
NSUI's Arun Hooda won the President's post while Varun Khari was declared the new Vice-President.
Varun Chaudhary was elected the secretary while Raveena Choudhary became the joint secretary.
The RSS-backed Akhil Bharatiya Vidyarthi Parishad (ABVP) had thumped NSUI in the elections last year bagging three of the four posts. The NSUI could only manage to win the post of President.
Delhi University, one of India's oldest, was established in 1922.
