The party advocated for the creation of a homogeneous Greater Tamil Nadu, incorporating Tamil-speaking areas of India and Sri Lanka.

In 1960, the party organised statewide protests in favour of the secession of Madras from India and the establishment of a sovereign Tamil Nadu.

In contrast, the BJP, INC, and DMK only allocated 16.3%, 14%, and 14% seats for women in Tamil Nadu, respectively, in the 2024 Lok Sabha election.

The party has launched several demonstrations demanding Tamil Nadu's share of Kaveri River and Mullaperiyar Dam water from upstream states.

This sparked unrest in the state, and NLC employees organised a strike against the central government's decision.

[32][33] The NTK opposed the decision, with Seeman saying that the Tamil strikers were experiencing discrimination from non-Tamil management.

He also criticised the NLC for investing in other Indian states during an acute power shortage in Tamil Nadu.

[35] Denying NTK involvement in an assault on a group of Sri Lankan tourists in Chennai, he said that the party abhors violence in any form and cadres who violate its principles of conduct would be punished.

[36] NTK has highlighted the plight of Sri Lankan Tamils who seek refuge in India, and their persecution by the state and central governments.

Moreover, it appealed for the inclusion of Sri Lankan Tamils into the Indian nation as fellow citizens and abolition of ill-treatment against them by the authority in any form.

In reply to this Seeman warned the government that he could reclaim Kachatheevu by arming fishermen, which resulted in sedition charges.

This gained public attention revealing that MK Stalin, the current Chief minister of Tamil Nadu is also a man of Telugu origin.

In spite of this Seeman's statement was criticised as racist, and he was accused of identity politics and creating ethnic divisions.

After the military defeat of the Liberation Tigers of Tamil Eelam in 2009 as a result of several war crimes and human rights abuses committed by the government of Sri Lanka and its nine different allies during the Sri Lankan civil war, the Eelam movement adopted non-violence for political solutions.

Additionally it appeals the United Nations Human Rights Council for the serving of justice to the Sri Lankan Tamils, who faced several war crimes such as systematically organized sexual assaults which is estimated in thousands,[55] massacres in hospitals and schools, driving away of people as a part of ethnic cleansing operations which led to a genocidal killing of 70,000 Tamil civilians as a part of War crimes during the final stages of the Sri Lankan Civil War.

[63] The NTK received 458,104 votes (1.1 percent) in the 2016 Tamil Nadu Legislative Assembly election, more than older parties such as MDMK, CPI, VCK, CPM and TMC.

[66] Seeman criticised the commission for not attempting to halt the bribery of voters in the constituency, asking about the location of promised CCTV cameras.

[67] Tamil news channel Puthiya Thalaimurai TV surveyed the constituency on which participating party was an alternative to DMK and AIADMK.

[73] NTK was the first party to field 20 women in the 2019 Lok Sabha elections for the total of 40 seats (39 in Tamil Nadu and one in Puducherry).

The party again fielded equal numbers of male and female candidates (117 women and 117 men in Tamil Nadu).
