Though the three seats where the BJP won saw a significant reduction in voter numbers, some of the seats where the party secured second position saw an increased voter count.
In contrast, the five Malappuram seats that registered the highest addition of voters post SIR saw a modest rise in turnout, in the range of 3 to 9 percentage points.
The roll has 8.97 lakh voters less than the electoral roll that was updated in October 2025 before carrying out SIR. The roll, before the exercise, had 2.78 crore voters.
