Congress general secretary B.K. Hariprasad Monday filed nomination for the Aug 29 bypoll to one Rajya Sabha seat from Karnataka and was set to be elected unopposed as he was the only candidate in the fray.
Nominations closed Monday.
The two other parties, Janata Dal-Secular and the Bharatiya Janata Party, did not field a candidate as they have only 40 members each in the 225-member assembly while the ruling Congress has 122.
The remaining are from smaller parties and independents.
The bypoll follows resignation of Congress Rajya Sabha member Anil Lad after he got elected to Karnataka assembly in the May 5 elections.
Chief Minister Siddaramaiah, several ministers and Karnataka Pradesh Congress Committee chief G. Parameshwara were with Hariprasad when he filed the nomination papers in the state assembly secretariat in city centre.
