The results of the polls will be declared Saturday.
The polling that started at 8.30 a.m. will end at 3 p.m. for the day colleges. The polling for evening colleges will be from 3 p.m. to 7 p.m.
The eligible voters from 50 colleges of the varsity will elect the Delhi University Students Union’s (DUSU) president, vice president, secretary and joint secretary.
There are seven candidates in the fray for the post of president, 32 for the post of vice president, 41 for secretary and 34 for the post of joint secretary.
The DUSU poll slugfest has always been between the National Students’ Union of India (NSUI), the Congress’ student wing, and the Akhil Bharatiya Vidyarthi Parishad (ABVP) which is the student wing of the Rashtriya Swayamsevak Sangh (RSS).
In the last election, ABVP had bagged the post of president, vice president and joint secretary, while the NSUI won the post of secretary.
In DU, the main agenda was hostel accommodation, issues of the northeast, while all organisations tried to take credit of scrapping the controversial four year undergraduate programme.
Delhi Police personnel have been deployed in colleges to ensure smooth functioning of election process.
