UP Election 2027 By-Elections Tracker: Results, Margins, and the Road to 2027
All 14 Uttar Pradesh Assembly by-elections since the 2022 general election, sortable, with a flip analysis against each seat's 2022 result. NDA won 10, SP
Uttar Pradesh has held 14 Assembly by-elections since the 2022 general election: 4 on 13 May 2024 (held simultaneously with the Lok Sabha general election), 9 on 20 Nov 2024, and 1 (Milkipur) on 5 Feb 2025. Across all 14, the BJP-led NDA won 10 and the Samajwadi Party won 4. But the more precise story is in the split: the 10 standalone contests held after the June 2024 Lok Sabha result was already known (the 9 Nov-2024 seats plus Milkipur) went 8-2 to the NDA — a cleaner read on momentum than mixing in the 4 May-2024 seats, which were contested under the same national conditions as the Lok Sabha race itself, not as standalone by-elections. Neither number is a statewide predictor — turnout is typically much lower than a general election, and voters often behave differently when only one seat, not a government, is at stake. As of Sep 2, 2026, one further vacancy exists (Faridpur, since 2 Jan 2026) with no by-election yet scheduled by the ECI.
BJP’s Rebound: Two Scorecards, Not One
Mixing seats contested under Lok Sabha-election conditions with genuinely standalone by-elections blurs the signal. Separating them gives a cleaner read on what happened after the Lok Sabha result was already known.
All 14 vs. the 10 Standalone Contests
The 20 Nov 2024 round alone was 7-2 for the NDA (BJP 6, RLD 1). Adding Milkipur’s BJP win (5 Feb 2025) brings the standalone total to 8-2. The 4 May-2024 seats split evenly (BJP 2, SP 2) — but those were contested during the Lok Sabha campaign itself, under national conditions rather than the more locally-driven dynamics of a standalone by-election, so folding them into the same tally as the later, standalone contests understates how one-sided the NDA’s recovery looked once the Lok Sabha result was behind both sides.
