Chief Election Commissioner (CEC) Kazi Rakibuddin Ahmed today said the overall achievement of the Election Commission to hold a free and fair Union Parishad polls has been marred as irregularities took place in some unions during the second phase polls.

"The 2nd phase UP polls were held in a peaceful manner, but our total achievement has gone in vain as irregularities took place in some unions during the polls," the CEC made the observation at a post-poll briefing held at the EC secretariat.

Voting at around 33 centres was suspended as the law and order situation went out of control, the CEC said.
