Tamil Nadu’s Electoral Integrity Under Scanner as ECI Investigates Foreign Nationals Voting in Assembly Polls

The Election Commission of India has launched a probe into allegations that foreign nationals cast votes in the recent Tamil Nadu Assembly elections. The controversy has raised serious questions about the credibility of the State’s electoral verification process.

Immigration officials detained nearly 25 foreign nationals, including citizens of Sri Lanka, the United Kingdom, Canada and Indonesia, during checks at Chennai and Madurai airports. Officials noticed indelible ink marks on their fingers, suggesting that they had voted in the April 2026 Assembly election despite carrying foreign passports.

The ECI has sought detailed reports from returning officers in at least two cities and five districts. Officials want to know how non-citizens remained on the electoral rolls despite a large-scale Special Intensive Revision conducted before the election.

Spotlight Falls on Electoral Roll Revision

The controversy has intensified scrutiny of the Special Intensive Revision process. Authorities designed the exercise to remove duplicate, deceased, shifted and ineligible voters through door-to-door verification.

Official figures show that Tamil Nadu deleted nearly 74 lakh names from the voter rolls during the exercise while adding around 27.5 lakh new voters. The latest revelations, however, have raised doubts over the effectiveness of the verification system.

Senior election officials are now examining whether people exploited provisions within the revision process to retain names of individuals who had moved abroad and acquired foreign citizenship.

One election official explained that the rules allowed an adult family member to submit enumeration forms on behalf of an absent relative. Investigators suspect some families may have misused this provision to keep foreign nationals of Indian origin on the electoral rolls.

Officials have not reached any final conclusion yet. However, several officers involved in the inquiry admitted that the case has exposed serious procedural weaknesses.

Airport Checks Triggered the Investigation

The alleged fraud surfaced after immigration personnel noticed indelible ink marks on passengers preparing to leave India shortly after the election. Officials later found that several detainees possessed Indian voter identity cards despite travelling on foreign passports.

Those detained included several Sri Lankan nationals along with individuals carrying British, Canadian and Indonesian citizenship. Officials described the possession of Indian voter cards by foreign passport holders as a direct violation of Indian law.

Investigators are analysing immigration records, polling data and electoral documents to determine how many foreign nationals may have voted. Authorities also suspect that some individuals may have left the country before officials intercepted them.

Police sources said intelligence inputs helped agencies identify suspicious travel patterns linked to the election period.

Criminal Charges Filed

Police have registered cases under Sections 172 and 318(2) of the Bharatiya Nyaya Sanhita, which deal with impersonation and cheating during elections. Authorities have also invoked Section 31 of the Representation of the People Act, 1950, which criminalises false declarations in electoral documents.

The controversy carries major political significance because it emerged after a fiercely contested election that reshaped Tamil Nadu’s political landscape.

Investigative agencies are now examining whether the case involves isolated violations or a wider network that facilitated fraudulent voter enrolment. The Election Commission will also assess whether the illegal votes affected the final election outcome after the investigation concludes.
