The Gaibandha-5 polls, which was postponed amid mass irregularities, will be held within 15 January, said Election Commissioner Rasheda Sultana.
She made the remarks during a press briefing at the election commission office in Dhaka's Agargaon on Monday.
In the by-election to the Gaibandha-5 constituency on 12 October, the EC ordered to stop the election midway after observing irregularities in one-third of the centres.
After that, Chief Election Commissioner Kazi Habibul Awal formed a three-member investigation committee to identify those involved in the irregularities.
On 1 December, Chief Election Commissioner (CEC) Kazi Habibul Awal said action will be taken against 134 polling officials for the reported irregularities and negligence in duties during the Gaibandha-5 by-polls.
