The vote concerns seats left vacant in four areas of the country. Available sources report that polling began on October 6.
According to Hindustan Times, the by-elections involve a total of six vacant seats. The figure is attributed to the publication, while the available information does not make it possible to establish unequivocally how the seats are distributed among the different legislative levels.
Hindustan Times links the vacancies to the resignations of incumbent legislators, submitted after the parliamentary and legislative elections of April 2026.
According to the same report, several legislators had stood as candidates in two constituencies and had subsequently retained only one of the two elected offices, leaving the other seats vacant.
The sources therefore place the by-election round across West Bengal, Tamil Nadu, Assam and Puducherry, without providing a complete list of the constituencies involved in the available material.
The start of voting is reported by both Hindustan Times and India Today. The point shared by the two sources is that the by-elections opened in the areas indicated, while the overall number of seats is explicitly attributed to Hindustan Times.
