New Delhi, Sep 3 - Over 40,000 students of Delhi University (DU) will Friday vote to elect a new students union amid a controversy over disqualification of several frontline student leaders' candidature.

Around 30 candidates will fight out for the four major posts - president, vice president, secretary and joint secretary. Over 60 colleges of the university participate in the Delhi University Students Union (DUSU) elections.

The polling for the day colleges will start 8.30 a.m. and end at 12.30 in the afternoon. For evening colleges, the timings will be 3-7 p.m.

The Delhi High Court Tuesday dismissed the petition of five candidates who had challenged their disqualification from the DUSU elections, saying the chief election officer had taken the decision in accordance with the rules.
