Kailash Choudhary is entering Parliament after defeating a Congress heavyweight, former Union minister Jaswant Singh's son Manvendra Singh.
He is the president of the Rajasthan unit of the BJP's Kisan Morcha and has been active on farmers' issues.
He won from Jat-dominated Barmer, the constituency which occupies the biggest area in Rajasthan, by a margin of over three lakh votes.
The Congress expected to win after fielding Manvendra Singh who had left the BJP in 2018, following differences with the then chief minister Vasundhara Raje.
The BJP picked Choudhary over its sitting MP even though he had failed last year to retain his Baytoo assembly seat, which falls under Barmer.
According to his nomination papers, Choudhary was convicted in 2002 a case of voluntarily causing hurt and wrongful restraint. He also has other cases pending against him.
