Lok Sabha expansion to 850 seats: Bill adopts ‘delimitation-first’ model, triggers federal concerns

The government argues that conducting a full delimitation after the 2027 Census could take considerable time, delaying the effective implementation of the 33% women’s quota. By opting for a delimitation exercise using 2011 Census figures and expanding the total number of seats, the proposal seeks to ensure that no state loses its current representation. Instead, all states are expected to gain additional seats, with larger, more populous northern states like Uttar Pradesh, Bihar, and Madhya Pradesh likely seeing numerically bigger increases due to their population shares.

New Delhi, April 14, 2026: The Union government has circulated a draft Constitution (131st Amendment) Bill, 2026, proposing a significant expansion of the Lok Sabha from its current strength of 543 seats to 850 seats. Of these, 815 seats would be allocated to states and 35 to Union Territories. The move, described as a “delimitation-first” approach, aims to fast-track the implementation of the women’s reservation law (Nari Shakti Vandan Adhiniyam) by enabling a fresh delimitation exercise based on the 2011 Census data, rather than waiting for the upcoming 2027 Census.

According to sources and reports, the government shared the draft bill with Members of Parliament ahead of a likely introduction during the special Parliament session beginning April 16. The proposal includes amendments to the Delimitation Act and related provisions to redraw constituency boundaries and reallocate seats while maintaining the existing proportional representation among states. This would allow one-third of the seats (approximately 283 in the expanded House) to be reserved for women without delaying their participation in elections, potentially from 2029 onwards.

# Rationale Behind the ‘Delimitation-First’ Model
The government argues that conducting a full delimitation after the 2027 Census could take considerable time, delaying the effective implementation of the 33% women’s quota. By opting for a delimitation exercise using 2011 Census figures and expanding the total number of seats, the proposal seeks to ensure that no state loses its current representation. Instead, all states are expected to gain additional seats, with larger, more populous northern states like Uttar Pradesh, Bihar, and Madhya Pradesh likely seeing numerically bigger increases due to their population shares.

Officials have emphasised that the relative share or proportion of seats for each state would remain unchanged in the initial expansion, addressing some immediate concerns about states “losing out.” The new Parliament building, with capacity for around 880 seats, is cited as infrastructure-ready for this change.

# Federal Concerns and Opposition Pushback
The proposal has triggered concerns over federal balance, particularly from southern states, the Congress, and regional parties. Critics argue that even a proportional increase in an expanded House could tilt political influence toward northern and central states with higher populations, potentially allowing them greater sway in government formation or constitutional amendments without needing broad consensus from southern or smaller states.

Congress leader Jairam Ramesh described the move as one that could “disadvantage” southern states, the Northeast, and smaller regions, warning that it might widen the north-south representation gap. Leaders from parties like the KC(M) in Kerala and others have flagged risks to cooperative federalism, fearing long-term political marginalisation of states that have successfully controlled population growth. Some voices have called for safeguards, such as a longer freeze on delimitation or a weighted formula for representation, to protect federal diversity.

Analysts point out that while the current proposal avoids immediate seat losses by increasing the overall size (estimates for a no-loss scenario have ranged around 848 seats in earlier discussions), future delimitation based on newer population data could still shift power dynamics. The new Parliament building’s design and the rotation of women’s reserved seats in single-member constituencies have also been noted as additional complexities.

# Broader Implications
If passed, the bill would mark one of the most significant overhauls of India’s parliamentary structure in decades, linking seat expansion directly to women’s empowerment while navigating demographic realities. Supporters view it as a democratic step that enriches representation without penalising any region upfront. Detractors see it as a politically calibrated move that may defer, rather than resolve, deeper federal tensions.

The government is reportedly seeking consensus among stakeholders. The delimitation process itself would involve a Delimitation Commission conducting public consultations before finalising boundaries and allocations.

As the special session approaches, the proposal is expected to dominate parliamentary debate, highlighting the delicate balance between equitable representation, population-based democracy, and India’s federal ethos.
