Thattanchavady, Oct 9:
The ruling AINRC retained the Thattanchavady Assembly constituency in neighbouring Puducherry, a seat considered the pocket borough of party founder and Chief Minister N Rangasamy.
The constituency fell vacant after Rangasamy resigned following his victory from both Thattanchavady and Mangalam in the April 9 Assembly elections.
AINRC candidate Ashok Anand won the bypoll with 13,358 votes, defeating his nearest rival by a margin of 8,482 votes. The counting was completed in four rounds.
Vinayagam secured 4,876 votes, while DMK candidate K Sethu, alias Sethuselvam, polled 2,664 votes, according to the Election Commission.
