The Kairana Lok Sabha seat fell vacant due to the death of BJP leader Hukum Singh in February.
The Rashtriya Lok Dal has fielded Tabassum Begam, who is likely to emerge as a joint candidate of the opposition, to take on the BJP in Kairana.
The BJP also announced that Avani Singh, the wife of late lawmaker Lokendra Chauhan, will be its candidate from Noorpur in the state.
The names for one Lok Sabha seat and four state assembly seats were finalised in the party central election committee today, the BJP said in a statement.
