The Jatiya Oikyafront and the BNP-led 20-party alliance will initially field multiple candidates all the 300 constituencies to avoid the risk of going to the polls without their contenders in some seats.
They have decided to employ this tactic keeping in mind that the Returning Officers (RO) might cancel some nomination papers during scrutiny on legal or technical grounds.
Sources in the Oikyafront, a combine of the BNP and several other parties, and the 20-party said they would nominate a panel of three to five candidates in each constituency for filing nomination papers.
The alliances will then pick a single candidate for each constituency on or before December 9, the last date for withdrawal of candidacies, and inform the RO of their decision in writing.
