Arka Sana: In a democracy, elections are meant to form governments. But in West Bengal, over the last three assembly elections, voters have sent a message that goes beyond choosing who will govern. They have also consistently reshaped the face of the opposition. Under Mamata Banerjee’s leadership, Bengal’s politics has witnessed a remarkable shift—not in the ruling party, but in the identity of the principal opposition.
🔄 2011: Winds of Change—In Government and Beyond
May 13, 2011. The date marked the fall of the longest-serving elected government in India—the Left Front’s 34-year rule came to an end. Mamata Banerjee swept to power on the back of a mass movement for “poriborton” (change).
But it wasn’t just the ruling party that changed. The post-Left era in Bengal politics also saw a revolving door in the Opposition ranks. Initially, the CPI(M) led the opposition with Surjya Kanta Mishra as Leader of the Opposition. In 2016, it was the Congress that took that spot with Abdul Mannan. And by 2021, both the Left and Congress were wiped out in the assembly, and the BJP rose to become the principal opposition, led by Suvendu Adhikari.
🧠 Why Does Bengal Keep Changing Its Opposition?
According to TMC’s Kunal Ghosh, the reason lies in credibility. “Mamata Di’s pro-people work has won the public’s trust, while the opposition has failed to earn confidence. That’s why voters keep switching camps,” he says. He also points to Mamata’s early success after breaking from the Congress in 1998 and forming the Trinamool Congress—a move that quickly earned her both electoral victory and ministerial power at the Centre.
CPM leader Mohammed Salim offers a more ideological take. “This isn’t just a regime change—it’s a collapse of the very political culture Bengal was known for. From social values to literature and political debate, everything has been distorted,” he argues.
Congress MP Adhir Ranjan Chowdhury believes the Left-Congress decline was deliberate. “Mamata weakened us to allow the BJP to grow. After all, neither is a threat to each other—they’re natural allies,” he claims.
On the other hand, BJP MP Shamik Bhattacharya asserts, “The BJP earned its space as the true alternative to the TMC.” Yet, he too agrees that Bengal’s political discourse has weakened over the years. “Once upon a time, Bengal thrived on healthy debate. That culture has eroded,” he laments.
🧭 Tracing the Opposition’s Journey: From Jyoti to Suvendu
In the 1950s, Jyoti Basu emerged as CPI’s prominent opposition voice in the assembly. In the 1960s, Congress leaders like Khagendranath Dasgupta and Siddhartha Shankar Ray took the lead during the United Front era. The 1970s saw CPI leaders like Bishwanath Mukherjee taking charge. Then came 34 years of uninterrupted Left rule from 1977 to 2011, during which Congress leaders like Abdul Sattar and Atish Sinha represented the opposition.
In the early 2000s, Trinamool rose as the main opposition with Pankaj Banerjee and Partha Chatterjee in key roles. After 2011, the cycle of change in the opposition resumed—and intensified.
🔍 From Left to Right: A Shift in Political Ecosystem
Many analysts suggest that Bengal’s voter psyche has transitioned from a Left-oriented political ecosystem to a more right-wing mindset over the years. From CPI(M) to Congress to BJP, the shift reflects not just political fatigue but also a deeper ideological migration.
And this shift isn’t entirely local—it is influenced heavily by national political trends as well.
🗳️ The Big Question for 2026: New Government, or Just a New Opposition Again?
If all goes according to schedule, Bengal will complete its next assembly election by this time next year. Will Mamata Banerjee continue to hold power? Or will a new force rise to challenge her? Perhaps the more telling question is—will the opposition reinvent itself again?
In Bengal, that’s become a trend worth watching.
