A day after the Sharad Pawar-led Nationalist Congress Party (SP) warmed to the Constitution (131st Amendment) Bill, 2026, which links delimitation with women’s reservation, the Shiv Sena (UBT) also signalled openness to the controversial proposal.The development comes on a day when Congress president Mallikarjun Kharge wrote to Prime Minister Narendra Modi urging him to convene an all-party meeting to discuss the Bill, while senior Congress leader Jairam Ramesh said the party was in touch with the entire Opposition and that the government would be unable to secure the two-thirds majority required to pass the legislation.Meanwhile, speaking to mediapersons in Nagpur on Thursday, Shiv Sena (UBT) leader and Rajya Sabha MP Sanjay Raut said the Opposition might reconsider its position on the Bill if the government incorporates the suggested amendments.“We will oppose the Delimitation Bill, but if necessary amendments as suggested by us are made, then the Opposition can think it over,” Raut said ahead of an important July 20 morning meeting of the Congress-led INDIA bloc scheduled to deliberate on Parliament strategy for the monsoon session starting that same day.On Wednesday, NCP (SP) working president Supriya Sule had also indicated that if the Delimitation Bill was based on a uniform 50 per cent increase in seats across all states, there would be little reason to oppose it. However, she later clarified in a post on X that no final decision had been taken and that the party would decide its stand on the Bill only after consulting other INDIA bloc partners and examining the draft once it is made public.Meanwhile, the government did not include the women’s reservation Bill in the tentative legislative agenda for the forthcoming Parliament session published on the Parliament website on Thursday.The Bill seeks to increase the strength of the Lok Sabha from the current 543 seats to 850 by raising each state’s seat quota by 50 per cent following a delimitation exercise. It further proposes to reserve 33 per cent of seats in the Lok Sabha and state legislative assemblies for women.Amid remarks by Sule and Raut, Jairam Ramesh today said the Congress was in touch with all Opposition parties, including the DMK and AAP, who had voted against the 131st Constitution Amendment Bill. Ramesh said the government would not be able to achieve a two-thirds majority in the Lok Sabha.These statements come at a time when the government is also engaging with political parties in an effort to secure support for the Bill when it is reintroduced. It is learnt that the government is also in touch with the MK Stalin-led DMK, which, alongside the Congress, was among the most vocal opponents of the Bill when it was introduced during a special session of Parliament in April.The Bill was defeated in the Lok Sabha after failing to secure the mandatory two-thirds majority of members present and voting, a constitutional requirement for the passage of a Constitution amendment Bill.The positions adopted by Opposition parties once the Bill is reintroduced, as expected, will test the cohesion of the Congress-led INDIA bloc and the depth of opposition unity on a key constitutional issue.
