The prominent contesting candidate left in the fray for Saturday bypoll is SAD's Ravinder Singh Brahmpura who faces six other candidates, including five Independents.
The poll campaign lacked the usual excitement as Congress had earlier announced "boycott" of the polls while new entrant AAP too had decided not to contest.
Last month, the nomination of Independent candidate Bhai Baldeep Singh, backed by Yogendra Yadav-led Swaraj Abhiyan, was rejected during scrutiny on the grounds that he was not a registered voter in Punjab.
The Congress had recently announced boycott of the by-election, with Punjab Congress President Amarinder Singh maintaining "since the basic issue of the sacrilege, for which Sikki resigned, still remains unresolved, the Congress party decided there was no point in contesting the election".
