Special Intensive Revision (SIR) deleted ~47 lakh names in Bihar elections concentrated in Seemanchal may tip results in 52 marginal constituencies during Nov 6–11 polls.

Bihar Elections 2025
The Election Commission’s Special Intensive Revision (SIR) of electoral rolls, launched nationwide on November 4, has placed Bihar at the centre of a high-stakes electoral question: will the deletion of roughly 47 lakh voters change the outcome of the state assembly elections scheduled for Nov 6 and 11? Analysts say the omitted names.
SIR’s regional impact is stark. Magadh, including Patna, saw the highest voter additions, while the Muslim-majority Seemanchal allege disproportionate removals and procedural errors, saying migrant workers and temporarily relocated voters were wrongly excluded. Opposition parties claim the roll revision risks disenfranchising traditional Mahagathbandhan supporters in seats where razor-thin margins decided results five years ago.
The Election Commission maintains the SIR exercise is accurate and robust, reporting an overall 5.9% deletion rate in Bihar and defending its verification protocols in the Supreme Court. Still, the political fallout extends beyond numbers.
