The Election Commission on Monday announced that bypolls for five Assembly seats across Tamil Nadu, Puducherry, and West Bengal, along with the Nagaon Lok Sabha seat in Assam, will be held on October 6, with votes to be counted on October 9.
Assam’s Nagaon Lok Sabha seat fell vacant in March this year when sitting lawmaker Pradyut Bordoloi, who won the constituency on a Congress ticket, resigned from the seat before he crossed over to the Bharatiya Janata Party and contested the assembly elections. Bordoloi won the Dispur assembly seat. Their move came after a faction of AIADMK legislators backed the TVK government in a floor test.
EC said the special intensive revision of electoral rolls for the constituencies concerned was completed between February 10 and February 28. However, it noted that the process of updating rolls will continue till the last date for filing nominations, based on applications received at least 10 days before that date.
Rangasamy won both Mangalam and Thattanchavady in polls held around the same time. He retained the Bhabanipur seat, from where he defeated Trinamool Congress chief Mamata Banerjee. The TMC has not responded to speculation that former chief minister Mamata Banerjee was considering contesting the Nandigram bypoll. In Puducherry, chief minister N. After being sworn in for a fifth term, he resigned from Thattanchavady while retaining Mangalam.
West Bengal chief minister Suvendu Adhikari vacated the Nandigram seat after winning the seat along with Bhabanipur in the May 2026 assembly polls. Adhikari had previously also defeated Banerjee from Nandigram in 2021.
