Jannayak Janta Party leader Dushyant Chautala was leading over his nearest BJP rival Prem Lata from Uchana Kalan constituency in Haryana's Jind district.
The JJP leader has attained a comfortable lead of 10,420 votes over Lata, who is a sitting MLA and wife of former Union Minister Birender Singh, according to latest trends.
Dushyant is a former MP from Hisar, who floated the JJP last year after a vertical split in the INLD following a family feud in the Chautala clan.
