Bengal Beyond Mamata Banerjee: Who Can Fill the Space She Leaves Behind?

By MANISH ANAND

Senior Congress leader Digvijay Singh says “vacuum in politics doesn’t last.” Who in West Bengal will take the Opposition space, the analyst decodes.

New Delhi, June 17, 2026 — The rise of the Bharatiya Janata Party (BJP) in West Bengal has brought an inflection point in the state politics. Post poll implosion in the Mamata Banerjee-led Trinamool Congress has left the Opposition rudderless. As West Bengal presents a semblance of a single party domination, veteran politicians and political observers are weighing the crucial question: who will fill the resultant vacuum in the Opposition space in the state?

The TMC implosion after the West Bengal Assembly elections has resulted in over two-thirds of the Opposition MLAs breaking ranks with the Mamata Banerjee-led outfit, and seemingly aligning with the ruling BJP. The same fate fell on the TMC at the national stage. Twenty MPs of the TMC in the Lok Sabha merged into a mysterious Tripura-based political outfit called the Nationalist Citizens Party of India (NCPI).

The net result in the West Bengal politics following is a sense of an Opposition vanishing after the BJP wrested power in Nabanna. The rise of the TMC in West Bengal was defined by Mamata Banerjee wresting the anti-Left space. She had defined a campaign against the Left rule in West Bengal.

Now, the politics of West Bengal per seasoned observers is fundamentally altered. The pivot that the Left had held for 34 years in West Bengal had passed on to the TMC. After 15 years, the BJP finally grabbed the anti-TMC space to gain the political pivot in West Bengal. Who will fill the void created by the rupture in the TMC and grab the anti-TMC space?

Senior Congress leader Digvijay Singh asserts that there’s no scope for a vacuum in politics. “Someone will fill it. There cannot be a vacuum,” Singh told this author, while discussing the emerging trends in the national politics.

Kolkata-based political observers have argued that the Left cadre in West Bengal is intact. In the 2019 Lok Sabha elections and 2021 Assembly polls, the Left cadre had tactically supported the BJP. This is a sweeping view among political observers in Kolkata. The emerging view for the 2026 Assembly elections in West Bengal also retains the same view.

“Now that the TMC has been voted out, and the party is in a state of ruins, the Opposition space is up for grabs. Mamata Banerjee seems past her prime. Her nephew, Abhishek Banerjee — the chosen heir of the TMC, has been exposed for an inadequacy in leadership capabilities,” said a senior Kolkata-based political leader.

His verdict: “The Left with its cadre intact will rise in West Bengal and speedily fill the void left by the TMC. The Congress due to a lack of cadre strength cannot beat the Left for that space. The Left will make a strong comeback in the state politics.”
