As per the schedule, polling in Avanigadda will now be held on August 21 and counting of votes on August 24.
Telugu Desam Party has fielded Ambati Sri Hari Prasad, son of sitting MLA Ambati Brahmanaiah whose death caused the by-election, and requested Congress, YSR Congress and other parties not to field their candidates to make the election unanimous keeping with the tradition.
The political parties consented and communicated their decision not to field their candidates to TDP chief N Chandrababu Naidu.
But two independents refused to withdraw from the fray despite a plea made by TDP district president and MLA Devineni Umamaheswara Rao.
Party sources here said their district leadership failed to convince the independents from withdrawing though Chandrababu cleared the way by making the political parties accept his request not to field their candidates.
