The Home Ministry has clarified that the demarcation process proposed by the Center will not reduce the representation of southern states in the Lok Sabha. Instead, the document says all states will gain seats proportionately under an expansion model linked to a 50% increase in parliamentary strength.
Union Home Minister Amit Shah, who intervened in the Lok Sabha debate on the Delimitation Bill, 2026, the Constitution (131st Amendment) Bill, 2026, and related amendments, said there was a “misperception” that the southern states would lose representation.
The government plans to Increase the total number of Lok Sabha seats by about 50%. This means that the number of seats in the House of Representatives will grow from 543 seats to 816 seats. The lower house of Parliament has 545 seats, of which two seats are reserved for the Anglo-Indian community.
According to him, the exercise will ensure that no state experiences a decline in its seat share, even as the total number of seats increases.
What is being suggested
- Boundary demarcation based on the 2011 census.
- Expansion of Lok Sabha strength from 543 to 816 seats (50% increase model).
- Implementation of 33% reservation for women.
- Apply only after the 2029 elections; There is no change in the current elections
The center also said it had not changed The Demarcation Commission Act, and that the existing legal framework has been reproduced without changes.
What the government claims
While the total number of members of Parliament will increase, each state’s percentage share of seats will remain virtually unchanged, according to a press release from the Ministry of Home Affairs.
The southern states currently hold 129 seats out of 543 (23.76%). After the proposed expansion, it will rise to 195 seats out of 816 (23.87%).
The remaining 621 seats (about 76% of the House of Representatives) will go to other states, especially in the north.
The government says this shows that the south’s overall share remains stable at around 24%, even after the border is demarcated.
South India’s seat share in Lok Sabha
Karnataka
- Current: 28 seats (5.15%)
- Proposal: 42 seats (5.14%)
Andhra Pradesh
- Current: 25 seats (4.60%)
- Proposal: 38 seats (4.65%)
Telangana
- Current: 17 seats (3.13%)
- Proposal: 26 seats (3.18%)
Tamil Nadu
- Current: 39 seats (7.18%)
- Proposal: 59 seats (7.23%)
Kerala (Keralalam)
- Current: 20 seats (3.68%)
- Proposal: 30 seats (3.67%)
In all five states, the total number of seats increased from 129 to 195, while the proportional share remained almost unchanged.
| state | Current seats | Current home percentage | New seats | % fresh from home |
| Tamil Nadu | 39 | 7.18% | 59 | 7.23% |
| Karnataka | 28 | 5.15% | 42 | 5.14% |
| Andhra Pradesh | 25 | 4.60% | 38 | 4.65% |
| Telangana | 17 | 3.13% | 26 | 3.18% |
| Keralam | 20 | 3.68% | 30 | 3.67% |
| Total South | 129 | 23.76% | 195 | 23.87% |
Government plan
According to Amit Shah’s statement:
- No state, especially in southern India, will face less representation.
- Seat increases will follow a proportional and uniform model.
- This practice will be based on the current law, without making changes to its text.
- Implementation will not take place until after 2029.
- Current elections, including in Tamil Nadu and West Bengal, will not be affected.
The government also said that the demarcation process is constitutionally required and will only come into effect after approval by Parliament and the Presidency.
India has demarcated the border only three times since independence, in 1951, 1961, and 1971. The process has been frozen for decades to balance population control efforts with political representation.
Class census
Amit Shah said that the Federal Cabinet approved A Class census. He explained that caste data will be collected in the second phase of the census during the individual enumeration. The first phase, currently underway, only counts households and does not collect any class information.
Why does the debate continue?
Although the government says the changes will be fair and proportionate, concerns remain. The northern states are expected to gain more seats in absolute numbers due to higher population growth.
Southern states worry that even if their percentage share of seats remains the same, their real political influence may diminish over time. Opposition parties also say this could slowly shift more national power towards the northern states.
MK Stalin was among the harshest critics. the The Tamil Nadu Chief Minister described the proposal as a potential “historic injustice” and warned that it could dilute the voice of southern states in national decision-making. He also burned a copy of the bill.
The three draft laws presented to Parliament
The three bills presented by Law Minister Arjun Ram Meghwal in Parliament on Thursday are:
- Constitution Bill (Amendment No. 131), 2026
- Draft Boundary Demarcation Law, 2026
- Federal Territories Laws (Amendment) Bill, 2026
The House of Representatives is scheduled to hold a final vote today at 4 p.m.
