India’s 2026 state-election results produced a sweeping political churn across four states, with actor-turned-politician Vijay’s Tamilaga Vettri Kazhagam (TVK) emerging as the single largest party in Tamil Nadu and Prime Minister Narendra Modi’s BJP ending Mamata Banerjee’s 15-year hold on West Bengal.

Final figures from the Election Commission of India, with all 234 Tamil Nadu seats declared, gave TVK 108 in its maiden electoral contest, the DMK-led alliance 73 and the AIADMK-led alliance 53, Newswire reported on Tuesday. The party fell ten seats short of the 118 needed for an outright majority and is now expected to seek post-election alliances. Vijay called the mandate “a people’s victory” and “the beginning of a new political era.”

Chief Minister M.K. Stalin formally conceded defeat in a post on X overnight, then submitted his resignation letter to the Governor’s office. “We bow to and accept the verdict of the people. Congratulations to the victors!” he wrote, according to Daily Mirror, adding that the DMK would now serve as an “exemplary Opposition” after defending the party’s five-year record on welfare and development. He had earlier lost his Kolathur stronghold to TVK joint general secretary V.S. Babu by around 9,000 votes — Babu polling about 82,000 to Stalin’s 73,000 — in what Newswire called one of the biggest upsets in the state’s history. More than a dozen DMK ministers also lost, with Stalin’s DMK reduced from a sweep in 2021 to opposition status.

Governor Rajendra Vishwanath Arlekar — currently serving as Governor of Kerala and holding additional charge of Tamil Nadu since March 2026 — is expected to act on the resignation. After tendering it, Stalin updated his X profile to identify himself solely as DMK president, dropping the “Chief Minister” designation, Newswire and Ada Derana reported on Tuesday. The DMK alliance secured roughly 1.54 crore votes; Stalin noted the winning side led by 17.43 lakh votes, a 3.52 percentage-point margin.

In West Bengal, the BJP’s victory ranked among the most significant breakthroughs of Modi’s 12-year tenure, ending Banerjee’s three-term Trinamool Congress government in a state with an electorate larger than Germany’s, The Island reported. The BJP polled more than 44% of the vote after years stuck near 39-40%. In Kerala, the Congress-led United Democratic Front defeated the Left Democratic Front after two consecutive LDF terms, ending the last Communist-led state government in India. Only in Assam did the BJP retain power, while the party also held the federal territory of Puducherry.

The Tamil Nadu result carries direct implications for Sri Lanka. The DMK has historically been the loudest Indian voice on Sri Lankan Tamil minority rights, war-crimes accountability and the recurring Palk Strait fisheries dispute that has sparked diplomatic friction over Indian fishermen detained in Sri Lankan waters. Vijay, 51, has not yet outlined a Tamil Nadu policy on Sri Lanka.
