Recent political developments involving the Trinamool Congress (TMC) and Shiv Sena (Uddhav Balasaheb Thackeray) have ignited fresh discussion over the BJP-led National Democratic Alliance (NDA). Whether they can move closer to the two-thirds majority required to pass major delimitation amendments is the one of the biggest discussions.

The debate gained momentum after reports of a split within the TMC and signs of rebellion among MPs belonging to the Shiv Sena (UBT). While the numbers have improved for the ruling alliance, the NDA remains short of the required numbers for constitutional amendments in both Houses of Parliament.

Why does the two-thirds majority matter? Constitutional amendments require approval by a special majority in Parliament. Earlier this year, the government introduced bills linked to delimitation and the implementation of women's reservation. But failed to secure the required support. The proposed legislation requires a stronger parliamentary majority than the NDA currently possesses.

Delimitation refers to the redrawing of parliamentary constituencies based on population changes. Several opposition parties, particularly from South India, have raised concerns about fresh delimitation exercise. They argue that delimitation could alter the balance of representation in the Lok Sabha.

NDA's current position in the Lok Sabha According to recent parliamentary calculations, the NDA currently holds 293 seats in the 540-member Lok Sabha. A two-thirds majority would require support from around 360 members.

The alliance's strength could rise if rebel MPs from opposition parties back the NDA. Reports suggest that seven rebel TMC MPs and six rebel Shiv Sena (UBT) MPs could support the ruling alliance. If that happens, the NDA's strength in the Lok Sabha could rise from 293 to 316 seats. Even then, it would remain more than 40 seats short of the two-thirds mark of 360.
