The BJP recorded major victories in West Bengal's Nandigram and Rezinagar Assembly constituencies and won Assam's Nagaon Lok Sabha seat in the bypolls. The NDA also gained Thattanchavady in Puducherry through its ally AINRC, while Tamil Nadu's TVK won Dharapuram and Madurantakam.
The results covered 4 states and one Union territory, according to the report. They have prompted reactions from the BJP, Congress, regional parties and leaders across the affected states.
BJP's breakthrough in Rezinagar
The most closely watched result came from Rezinagar, a Muslim-majority constituency in West Bengal where the BJP won for the first time. Shankarao Sarkar received 1,29,914 votes and defeated Aam Janata Unnayan Party candidate Golam Nabi Azad, also known as Robin, by 75,816 votes.
Congress candidate Abdullahil Kafi received 6,168 votes, while Trinamool Congress candidate Rabiul Alam Chowdhury received 3,847 votes. The result marked a significant expansion in the BJP's vote total in the constituency.
Prabal Laha, appointed the BJP's election in-charge for Rezinagar, said the party had succeeded in reaching Muslim voters with its message. He linked the result to the party's “Sabka Saath, Sabka Vikas” slogan and its development promises.
During the campaign, West Bengal Chief Minister Shubhendu Adhikari appealed to minority voters to support the BJP on development issues. He spoke about work involving hospitals, bridges, colleges and employment, and also promised to bring migrant workers back.
After the result, Adhikari claimed that around 60% of Muslim votes in Rezinagar and around 80% of Muslim votes in Nandigram had gone to the BJP. These figures were presented as a political claim after the counting.
The report also said the BJP's Rezinagar vote rose from 64,660 in the 2026 Assembly election, when Bapan Ghosh contested, to 1,29,914 for Sarkar in the bypoll.
Nandigram and Nagaon results
In Nandigram, BJP candidate Hasirani Rath defeated Congress candidate Milan Pradhan by 1,22,753 votes. Pradhan received 41,674 votes. Mamata Banerjee had supported the Congress candidate, but the support did not translate into a victory.
BJP leaders also claimed that minority voters backed the party in Nandigram. Turnout in both West Bengal constituencies was reported to be around 80%.
In Assam's Nagaon Lok Sabha constituency, BJP candidate Debashish Sharma won with 47,402 votes. AIUDF chief Badruddin Ajmal finished second with 21,107 votes, while Congress candidate Sibamoni Bora was third with 6,544 votes.
The Nagaon bypoll followed the resignation of Congress MP Pradyut Bordoloi. He left the Congress, joined the BJP and contested the Assembly election, after which the parliamentary seat became vacant.
Following the defeat, Congress alleged vote theft. Assam Chief Minister Himanta Biswa Sarma responded that the party made such allegations whenever it lost an election. Raijor Dal founder Akhil Gogoi urged Congress to conduct an introspection and demanded the resignation of Assam Congress president Gaurav Gogoi. Ajmal described Congress as the BJP's “B team” and blamed it for his party's defeat.
Results in Puducherry and Tamil Nadu
In Puducherry's Thattanchavady Assembly seat, AINRC candidate Ashok Anand won for the NDA. The constituency fell vacant after Chief Minister N. Rangasamy won from 2 seats and chose to retain Mangalam instead of Thattanchavady.
The outcome gave the NDA another seat in the Union territory. AINRC is an ally of the NDA.
Tamil Nadu's ruling TVK won both Dharapuram and Madurantakam. P. Sathyabama defeated DMK candidate Suganya S. by 9,471 votes in Dharapuram, while K. Maragatham Kumaravel defeated DMK candidate I. Paranthamen by 20,040 votes in Madurantakam.
Both constituencies had previously been represented by AIADMK legislators. The bypolls were held after those legislators resigned from the Assembly and joined TVK.
After the DMK's defeat, former Tamil Nadu Chief Minister M.K. Stalin criticised Vijay's party. He called the victories “an interim win achieved through betrayal” and said the decline of “politics based on a fake ” had begun.
Political reactions and election concerns
Prime Minister Narendra Modi thanked voters for what he described as continued support for the BJP and NDA. He said the results reflected people's connection with the parties' good-governance agenda.
Union Home Minister Amit Shah accused the Opposition of spreading lies, confusion and propaganda. BJP general secretary Smriti Irani also targeted Rahul Gandhi over his statement that he was fighting the Indian state.
The bypolls took place amid Opposition questions about the functioning of the Election Commission. Allegations of irregularities, voter intimidation and malpractice were reported during polling in West Bengal. Congress sought repolling in Nandigram and Rezinagar, while the BJP rejected those allegations.
Conclusion
The bypoll results gave the BJP strong victories in West Bengal and Assam, added a seat for the NDA in Puducherry, and established TVK's wins in two Tamil Nadu constituencies as another major feature of the contest. The results also triggered fresh debate over voter support, Opposition strategy and election-related allegations.
