en.wikipedia.org/wiki/2026_Kerala_Legislative_Assembly_election

The claim is referring to the Indian National Congress's performance in the previous Kerala Assembly election (2021). Official Election Commission of India results for Kerala show Indian National Congress — Won: 21. An official Kerala Assembly results summary also lists the INC as having 21 seats won with 25.12% vote share.

So the vote-share part (25.12%) is correct, but the seat count is not: it should read 25.12%, 21 seats, not 22 seats.

This also means any seat-change figure derived from 22 would be off by one.
