Prashant Kishor, founder of the Jan Suraaj Party, won the Bankipur assembly by-election in Bihar, ending the BJP's three-decade hold on the seat [4, 5].

The victory represents a significant shift in the political landscape of the Patna district. By defeating the BJP in a traditional stronghold, Kishor has demonstrated the viability of his Jan Suraaj movement as a competitive electoral force in Bihar.

Kishor secured 64,151 votes [2]. While reports on the exact victory margin vary slightly, the gap between Kishor and the BJP candidate ranged between 19,246 [4] and 19,324 votes [1]. During the counting process, Kishor maintained a lead of 6,646 votes after the first 12 rounds [3].

The Bankipur constituency had been held by the BJP for 31 years [5]. This long-term dominance was disrupted by a campaign that focused on local issues and capitalized on anti-incumbency sentiment [6].

Kishor's win marks the first major legislative breakthrough for Jan Suraaj in the region. The campaign's ability to peel away voters from a party that had controlled the seat for over three decades suggests a weakening of the BJP's base in certain urban Bihar sectors [6].
