The Election Commission will hold bye-election on October 13 to Tiruchirappalli West assembly seat, which fell vacant following the death of AIADMK member Mariam Pitchai.
Mr. Pitchai, who was inducted as a minister in the Jayalalithaa ministry, was killed in a road accident even before he could take oath as a member of the assembly. The State government had already ordered a CB-CID probe into the accident.
This will be the first by-poll after AIADMK and its allies swept the Assembly 13 elections.
The election also comes in the midst of a spate of arrests of DMK leaders on land grab charges. Tiruchirapalli DMK strongman and former Transport Minister K N Nehru is also in jail for alleged land grab charges.
The by-poll comes ahead of the local body polls and the State government had announced holding the elections in the last week of October when their term come to an end.
The EC also announced bye-election to Indira Nagar assembly constituency in Puducherry on the same date.
According to the poll schedule, notification will be issued on September 19. Last date for making nominations is on Sept 26 and scrutiny will take place the next day. Last date for withdrawal of candidatures would be on September 29.
Counting of votes will take place on October 17.
