The Constitutional Amendment bill's implementation is tied to a population-based revision of constituencies based on the 2011 census. It proposes delimitation - a wider political overhaul - aiming to change the size and composition of state legislative assemblies and Lok Sabha

The protest by DMK leaders, including RS Barathi, TKS Elangovan, and Kanimozhi Somu, was carried out at the party's headquarters in Chennai. The protesting leaders burned a copy of the proposed delimitation bill and raised slogans against the ruling Bharatiya Janata Party (BJP) in centre

M K Stalin also raised a black flag to kick off statewide anti-delimitation agitation. The opposition has also objected to haste in convening a special Parliament sitting amid the election season

The government is planning to implement the women's reservation ahead of the 2029 General Elections by bringing in an amendment to the 2023 Act and a constitutional amendment to delink the delimitation process from the 2027 census

The government has proposed to increase the number of seats in the House to 850, with 815 seats proposed for the States and the remaining 35 for the Union Territories. The Lok Sabha has 543 seats at present
