The rebellion in the Trinamool Congress ranks, especially in its parliamentary party, has revived talk that the government is likely to bring the Delimitation Bill as early as the Monsoon Session, likely to start mid-July.

The Constitution (One Hundred and Thirty First Amendment) Bill, 2026, or the Delimitation Bill, which sought to redraw electoral boundaries based on the 2011 census, was defeated in Parliament in April as it fell short of the two-thirds majority required for its passage. The Women’s Reservation Amendment Bill had been bundled up with the Delimitation Bill and that too consequently bit the dust.

Much has changed since then in the political scene with the Trinamool Congress’s defeat in the West Bengal Assembly election and the fast disintegration of its ranks. Just like in the case of the Shiv Sena and the Nationalist Congress Party (NCP) splitting and their rebel groups joining the NDA ranks, and later the Rajya Sabha MPs from the Aam Aadmi Party (AAP) doing the same, government circles are sensing an opportunity in the scatter in the Trinamool.

On Monday (June 8, 2026), Trinamool MP Kakoli Ghosh Dastidar claimed to have the support of 20 party MPs in the Lok Sabha, one more than required to split the party as per the anti-defection law.

Sources in the government have said that senior strategists of the ruling party are again in touch with various parties, including the DMK and the Samajwadi Party (SP), regarding a rethink on voting on the Bill. Sources also said that the government will not be bundling up the Delimitation Bill and the amendments to the Women’s Reservation Act this time, and may even make some revisions to the provisions of the Bills if enough parties say they are on board.
