Counting of votes for by-elections to Assembly constituencies in Tamil Nadu, West Bengal and Puducherry, along with a Lok Sabha constituency in Assam, will take place on Friday, with the results expected to provide an electoral indicator for the parties involved. 

In Tamil Nadu, counting will be held for the Madurantakam and Dharapuram Assembly constituencies, with the outcome set to provide an early electoral test for Chief Minister C. Joseph Vijay's Tamilaga Vettri Kazhagam (TVK) government.
