The Bharatiya Janata Party is set to form its first government in West Bengal, crossing 200 seats in the 294-member assembly, marking the end of the Trinamool Congress's 15-year rule. Chief Minister Mamata Banerjee lost the Bhabanipur seat to BJP's Suvendu Adhikari, confirming a major political shift in the state.

In Tamil Nadu, actor-turned-politician Vijay's Tamilaga Vettri Kazhagam (TVK) emerged as the single-largest party with 108 seats, overtaking the DMK and AIADMK. Vijay visited the party headquarters in Chennai to meet winning candidates as efforts begin to form the next government.

The BJP retained power in Assam for a third consecutive term under Chief Minister Himanta Biswa Sarma, securing a comfortable majority. In Kerala, the Left Democratic Front was wiped out, with the Indian National Congress winning 63 seats to claim victory.

Prime Minister Narendra Modi called the results a mandate for 'politics of performance,' while opposition leaders alleged irregularities and demanded verification of electronic voting machine counts. Election Commission officials confirmed the results were based on authenticated vote tallies.

The President has called for the formal swearing-in of new chief ministers in West Bengal and Kerala within seven days, while Tamil Nadu's governor has invited TVK to prove majority on the floor of the Assembly by June 12.
