543 Vs 850, Delimitation Math & Rationale: The government plans a uniform 50% increase in seats for all states, says Amit Shah. News18 explains the numbers

Union Home Minister Amit Shah, in the House on Thursday, explained that the government plans to increase the total number of seats from the current 543 to a maximum of 850 to accommodate the 33% women’s reservation without reducing the existing representation. Amid opposition’s concerns, Shah clarified that the Modi government has not made any changes to the formula for composition of Delimitation Commission and the norms are the same as during the Congress-led United Progressive Alliance (UPA) government.

543 vs 850, News18 explains.

How was the number 850 arrived at?

The Constitution (One Hundred and Thirty-First Amendment) Bill, 2026, The Union Territories Laws (Amendment) Bill, 2026 and The Delimitation Bill, 2026 were introduced and taken up for consideration and passing in the Lok Sabha on Thursday.

Amit Shah sought to allay apprehensions of opposition members about the Southern states losing their influence as a result of an increase in seats in the Lok Sabha to implement the women’s reservation Act, and said that while there will be about a 50 per cent increase in their seats, the relative proportion in total seats will also move up.

“The biggest narrative being created is that these three bills, the Constitution Amendment Bill, the bill on delimitation, and changes to the constituency election law, will harm the power of the South," he said.

The logic

Shah provided a specific mathematical rationale for why the number 850 was chosen.

The government plans a uniform 50% increase in seats for all states. Shah explained that if you have 100 seats and want to reserve 33% for women, increasing the total seats by 50% makes it 150. When 33% is then reserved from 150, you are left with 100 seats for general competition.

A 50% increase from 543 results in exactly 816 seats. Shah clarified that 850 is a rounded upper limit, with 815 seats allocated to states and 35 to Union Territories.

The numbergame decoded: The southern worry

“If we listen to the entire narrative created for the South, then out of the 543 seats created by you, 129 MPs currently sit in this House, which is approximately 23.76%. In the new House, 195 MPs will be sitting here, and their power will be 23.97%," he added.

Shah said Karnataka has 28 seats, and 5.15 per cent of the 543 seats in the House and after the passage of the bill, the number of Karnataka MPs will increase from 28 to 42, and the percentage in the Lok Sabha will increase to 5.44.

“Karnataka will not suffer any loss at all. Andhra Pradesh has 25 seats, which is 4.60 per cent. After the passage of the bill, the number of MPs will increase from 25 to 38, which will be 4.65 per cent," he said.

Shah said Telangana has 17 seats, which is 3.13 per cent and after the passage of the bill, the number of MPs will increase from 17 to 26, which will be 3.18 per cent.

“Tamil Nadu has 49 seats, which is 7.18 per cent. After the passage of the bill, the number of MPs will be 59, and their percentage in the new House of 816 will be 7.23 per cent. Tamil Nadu will also suffer no loss. Keralam has 20 seats, which is 3.68 per cent. After the passage of the bill, the number of MPs will be 30, and their percentage in the new House will be 3.67 per cent," he added.
