October 9 bypoll results: Key numbers

6: seats counted.

3: seats won by the BJP.

2: seats won by the TVK.

1: seat won by the AINRC.

8,482: the AINRC’s winning margin in Thattanchavady.

Rejinagar’s margin was 75,816 votes in the main report, and other live items gave figures such as 75,691.

In Assam’s Nagaon Lok Sabha seat, the BJP’s Devasish Sharma won, ahead of the AIUDF’s Badruddin Ajmal.

The Sentinel reported Sharma’s margin as 1,42,224 votes, while ETV Bharat gave 1,40,257, so the margin is about 1.4 lakh.

The Congress’s Sibamoni Bora finished third in Nagaon, according to the Sentinel.

Assam Chief Minister called the win a tribute to the Prime Minister’s leadership, according to ETV Bharat.

In Tamil Nadu, the ruling TVK won both Madurantakam and Dharapuram.

In Madurantakam, TVK’s K. Maragatham Kumaravel won by about 20,000 votes over the DMK, according to India TV and ETV Bharat.

A live blog by DT Next gave an earlier-stage margin of 19,312 for Madurantakam, so the final margin should be checked against the Election Commission’s figures.

In Dharapuram, TVK’s Sathyabama polled 66,841 votes against 57,370 for the DMK, and the margin was 9,471 votes, according to ETV Bharat.

The DMK finished second in both Tamil Nadu seats and the AIADMK third, according to ETV Bharat.

In Puducherry’s Thattanchavady, the AINRC’s Ashok Anand won by 8,482 votes over the Congress’s E. Vinayagam, according to India TV.

Anand polled 13,358 votes against 4,876 for Vinayagam, and the DMK’s K. Sethu got 2,664.

The seat fell vacant because N. Rangasamy won two constituencies in April 2026 and kept Mangalam.

Rangasamy had won Thattanchavady by 4,441 votes in April, so the margin of 8,482 is nearly double that.

Turnout at the bypolls was highest in Madurantakam at 85.99% and 80.81% in Thattanchavady.

Reports differ on exact margins and name spellings, and the official figures are those of the Election Commission of India.
