As Opposition parties across India raise alarm over the BJP’s bid to enforce a population-based delimitation at the national level, the DMK in Tamil Nadu, which can see the writing on the wall, is up in arms. Chief minister M.K. Stalin even burnt a copy of the proposed bill in Namakkal and hoisted a black flag in rejection of a ‘black law’.

The party argues that a delimitation exercise that is driven solely by population risks altering the democratic balance and weakening India’s federal structure. Salem Dharanidharan, national spokesperson of the DMK, tells K.A. Shaji why delimitation must move beyond numbers and reflect both demographic realities and governance outcomes.

What is the DMK’s proposed solution to the delimitation question?

The DMK’s position is anchored in constitutional precedent and political prudence. It argues that the current framework should continue for at least the next 25 years, much like earlier freezes that protected states that implemented national priorities such as population control. This continuity is necessary to prevent sudden distortions in representation and to preserve federal balance.

At the same time, the party calls for evolving a consensus-driven formula rather than imposing unilateral redistribution.

Population alone cannot be the determining factor because it ignores decades of policy choices that shaped demographic outcomes differently across states. Tamil Nadu’s sustained investments in public health and education brought down fertility rates significantly, while other states followed different paths. A purely population-based model would reward uneven growth and penalise governance success, which the DMK considers fundamentally unjust.

Should development indicators be considered alongside population?

The DMK believes this is central to any fair framework. Tamil Nadu ranks among the leading states in literacy, healthcare outcomes and social welfare delivery, with lower infant mortality and higher life expectancy than the national average. It is also one of the largest contributors to the Union’s tax revenues, supported by a diversified and industrialised economy. Reducing representation to population alone turns democracy into a mechanical exercise.

The DMK argues that human development indicators, fiscal contribution and governance efficiency must be factored in alongside demographic data. Without such balance, the system risks incentivising poor governance combined with higher population growth. Representation, in its view, must reflect both people and performance.

Is increasing the number of parliamentary seats a viable solution?

The DMK does not dismiss this possibility but insists it requires careful deliberation. India’s population has more than doubled since 1971 [in fact, 2.7x, from ~55 crore to an estimated 148 crore – Ed] while the number of parliamentary seats has remained unchanged, making expansion a logical consideration. However, such a move cannot be treated as a simple technical adjustment because it has significant implications for federal balance and political representation.

The party argues that any expansion must follow detailed discussions involving experts, political parties and states. It also stresses that representation should be strengthened across all tiers, including state Assemblies, panchayats and urban local bodies.

Strengthening these institutions is essential to deepen democracy at the grassroots. Only after reinforcing these layers should Parliament expansion be considered as part of a broader reform.

How can India reconcile a constitutional mandate with federal trust?

The Constitution provides both a framework and flexibility, as demonstrated by past decisions to freeze delimitation in the national interest. Reconciling mandate with trust requires a consultative process involving states, political parties and independent experts. Without such engagement, delimitation will be seen as an imposed exercise that favours certain regions.

Trust in federal institutions depends on transparency and inclusiveness. The DMK emphasises that democracy is not only about procedure but also about fairness. Any process that undermines this balance risks weakening the Union itself. Consultation and consensus are, therefore, essential.

Why has this issue resonated so strongly in Tamil Nadu?

The issue resonates because people understand the implications in concrete terms.

Tamil Nadu invested heavily in public health, education and social welfare, achieving stabilised population growth and improved quality of life. There is now a widespread perception that this success could translate into reduced political representation.

This creates a strong sense of injustice that goes beyond policy debate. The issue is seen as one of dignity and fairness. It is also linked to a broader sentiment that southern states are not adequately recognised for their contributions. This explains the depth and intensity of the response.

What is fundamentally at stake for southern states?

At stake is the balance of Indian democracy. If representation is determined purely by population, political power could become concentrated in a few regions, weakening the federal structure. This would also reshape national policy priorities in ways that may not reflect the diversity of the country.

Southern states contribute significantly to economic output and governance standards, yet their political voice could diminish. This creates a mismatch between contribution and representation. The DMK sees this as a structural issue with long-term consequences for India’s unity.

What is the DMK’s biggest concern about the current approach?

The concern goes beyond methodology to questions of intent and outcome. There is a perception that delimitation could be shaped to consolidate political advantage and reduce space for opposition. Such a shift risks deepening regional imbalances and altering electoral dynamics across the country.

There is also anxiety that regions with strong alternative political traditions may be weakened. This would influence not just representation but the nature of democratic competition. Without transparency and safeguards, these concerns become serious.

How does the DMK respond to the argument that representation must reflect population?

The DMK accepts that population is an important factor but rejects it as the sole basis. India is a Union of states, not a unitary system governed only by numbers. A purely population-based model ignores differences in governance, development and policy choices.

It risks concentrating power in regions with higher demographic growth while marginalising others. It also overlooks the role of public policy in shaping population trends. Representation must, therefore, balance demographic realities with development and federal equity.

Why does the DMK say Tamil Nadu is being penalised for success?

Tamil Nadu achieved significant reductions in fertility through sustained investments in healthcare, education and welfare. As a result, its population stabilised earlier than in many other states. If seats are redistributed purely on current population, states with higher growth gain more representation while Tamil Nadu’s share declines. This effectively penalises states that implemented national priorities responsibly.

Could this become a constitutional crisis?

At present, it remains a political issue that can still be addressed within the constitutional framework. The Constitution allows flexibility, as seen in earlier freezes on delimitation. This provides space for dialogue, negotiation and consensus-building. If the process is pushed through without addressing concerns, it could strain Centre-state relations, which could escalate into a constitutional crisis.

Is delimitation likely to become a long-term political faultline?

There is a strong possibility if handled without care. Questions of representation and federal balance have historically shaped Indian politics, and delimitation brings both into sharp focus. It also intersects with issues of regional equity, governance and democratic fairness. But it also presents an opportunity to strengthen federalism if approached with consensus.

As public campaigning for the Tamil Nadu assembly election drew to a close on the evening of 21 April, what began as a relatively confined constitutional debate within Parliament transformed into the single most defining political issue on the ground, reshaping the contours of the contest in its final phase and handing a clear narrative advantage to the DMK-Congress alliance. 

Delimitation, which until recently remained a subject of technical discussion and legislative contention, especially after it was voted down by a combined opposition in Parliament, acquired an emotional and political charge in Tamil Nadu that few other issues managed to generate during this election cycle. The DMK successfully framed it as an existential question of representation and identity, arguing that the state stood to lose disproportionately if the exercise were carried out in the manner proposed by the Narendra Modi and Amit Shah leadership at the Centre.

This framing did more than merely sharpen campaign rhetoric. It altered the balance of the contest by pushing the already fragmented Opposition, led by the AIADMK and including the BJP, into a defensive position from which it struggled to recover. The final days of campaigning, marked by intense mobilisation, roadshows, and sharp exchanges, increasingly resembled a collective assertion of Tamil Nadu’s political anxieties over the delimitation proposal. The issue cut across party lines among voters, creating a wider sense of unease that the opposition found difficult to counter convincingly. AIADMK leaders and their allies were repeatedly forced to clarify that they were not acting against Tamil interests, a position that appeared reactive rather than assertive in the face of a rapidly consolidating narrative.

Tamil Nadu’s electoral landscape is vast, layered, and historically complex, with 234 Assembly constituencies that reflect varied social coalitions, regional identities, and political traditions. Yet, in this election, the projection of delimitation as the central campaign issue by chief minister M.K. Stalin cut across these diversities and resonated widely. The symbolism was unmistakable. Large numbers of people turned up wearing black attire, even in the sweltering heat, as Parliament debated the bill, signalling not just political alignment but a shared sense of grievance.

Within the alliance, seat-sharing arrangements reflected both political pragmatism and underlying tensions. The DMK contested the lion’s share of 164 constituencies, while the Congress fielded candidates in 28 seats. The remaining constituencies were distributed among smaller allies, including the VCK, CPI, CPI(M), DMDK, MDMK, IUML, MMK, SDPI, and MJK, each of which holds influence in specific pockets. While murmurs of dissatisfaction emerged within Congress ranks over the allocation of winnable seats, and parties such as the CPI(M) expressed concerns about shrinking political space, these frictions were contained effectively. In districts like Sivaganga and Kanyakumari, local disagreements over candidate selection did surface, but they did not escalate into larger disruptions. The leadership ensured that the broader political message remained intact, with Stalin publicly acknowledging the role of Rahul Gandhi and Mallikarjun Kharge in opposing delimitation and reinforcing a sense of shared purpose.

In contrast, the opposition presented a far more disjointed picture. The AIADMK, still attempting to regain coherence after the demise of J. Jayalalithaa, continued to grapple with leadership ambiguity and internal factionalism. Its alliance structure appeared fluid, shaped more by local calculations than by a cohesive state-wide strategy. The BJP, which contested a significant number of seats either directly or through allies, invested heavily in campaign visibility, deploying central leaders and pushing a mix of national and cultural narratives. However, its long-standing structural limitations in Tamil Nadu remained evident, particularly when confronted with the delimitation issue. Party leaders struggled to reassure voters that the proposed changes would not harm Tamil Nadu, and even within the party there was a quiet acknowledgement of the difficulty in overcoming the prevailing perception.

This is not the first time the BJP has attempted to expand its footprint in the state. Over the years, it has experimented with multiple strategies, including alliances with both the DMK and AIADMK, emphasis on national security and welfare schemes, and efforts to build a local leadership base. Yet, these efforts have yielded only limited success. As C. Lakshmanan, a former faculty member at the Madras Institute of Development Studies, observes, “The reasons lie deep in Tamil Nadu’s political culture. The state’s electorate has consistently prioritised regional identity, linguistic pride, and social justice narratives shaped by the Dravidian movement. Attempts to impose a homogenised national political framework have often met with resistance. Policies perceived as central overreach, whether related to language, education, or resource allocation, have triggered strong reactions.” The delimitation debate fits squarely within this pattern of resistance.

At its core, the issue raises a fundamental question about representation and fairness. Tamil Nadu, which has successfully controlled population growth and achieved significant human development outcomes, fears that it could lose parliamentary representation precisely because of these achievements. The state’s fertility rate is among the lowest in India, while several northern states continue to record higher population growth. A redistribution of seats based purely on population would therefore shift political power away from states like Tamil Nadu, altering the federal balance in ways that many here view as unjust.

For voters, this concern is neither abstract nor distant. It has been framed as a direct and tangible loss, one that could reduce the state’s influence over national policy, weaken its bargaining power in fiscal matters, and diminish its voice within the Union. In a political culture that has historically asserted federal rights with clarity and conviction, this prospect has struck a deep chord. As political observer S Satheesh Kumar notes, “The DMK recognised the political potential of this issue early in the final phase. Chief minister M.K. Stalin’s campaign took on a sharper tone, positioning delimitation as a direct threat to Tamil Nadu’s interests. His speeches repeatedly emphasised that the state was being penalised for its achievements. The argument was simple, but it resonated widely.”

The Congress amplified this message at the national level, with Rahul Gandhi and Mallikarjun Kharge framing delimitation as a challenge to the federal structure itself. Their interventions elevated the debate beyond state politics, giving it constitutional significance and reinforcing the DMK’s position on the ground. In public meetings across Tamil Nadu, Congress leaders reiterated their commitment to resisting any move that could undermine the state’s representation, helping to bridge minor fissures within the alliance and present a unified front.

The response among the public was both visible and widespread. Black protests became a defining feature of the campaign’s closing days, with demonstrations taking place across Chennai, Coimbatore, Madurai, and smaller towns. Students, traders, farmers, and professionals participated in various forms, from wearing black attire to waving black flags and organising discussions. In Tirunelveli, college students held meetings explaining the implications of delimitation, while in the delta districts, farmers linked the issue to long-standing concerns over water sharing and perceived neglect by the Centre. In industrial hubs like Hosur, workers expressed apprehension that reduced political weight could affect future investments and policy attention.

The opposition’s response remained tentative and fragmented. The BJP attempted to reassure voters that delimitation would be conducted fairly and with adequate safeguards, arguing that fears were being exaggerated for political gain. However, these assurances failed to counter the growing perception of risk. The AIADMK, constrained by its political positioning, found itself unable to articulate a strong and independent critique, choosing instead to focus on governance issues, corruption allegations, and anti-incumbency narratives that struggled to gain traction in the face of the dominant discourse.

Underlying this entire phase of campaigning was a broader anti-Centre sentiment that has been building in Tamil Nadu over the past decade. Issues such as the National Education Policy, NEET, language debates, and fiscal devolution have contributed to a perception of increasing centralisation. Delimitation emerged as the most potent expression of this sentiment, encapsulating concerns about autonomy, identity, and fairness within the federal structure.

For the DMK-Congress alliance, this convergence of issues provided a strategic advantage. It allowed the alliance to reposition the election not merely as a judgment on governance but as a larger battle to protect Tamil Nadu’s rights and representation. In doing so, it also managed to subsume internal tensions under a unifying narrative, shifting the focus from seat-sharing disputes to the stakes involved for the state as a whole.

As the campaign closed, the election stood at a critical juncture, with delimitation having redefined the political conversation in its final phase. What began as a technical constitutional proposal evolved into a powerful political movement, exposing the limitations of the opposition and reinforcing the strengths of the DMK-Congress alliance. Tamil Nadu has long demonstrated a capacity to resist political currents it perceives as misaligned with its identity and interests. This election appears to have reaffirmed that instinct, turning a complex policy debate into a decisive electoral force that could shape the outcome when votes are finally counted.
