Mamata Banerjee vs Suvendu Adhikari: Bengal titans brace for round two in 2026 polls

Politics in West Bengal is hard to discuss without referencing one of its most defining rivalries — Chief Minister Mamata Banerjee versus Leader of Opposition Suvendu Adhikari. What began as a mentor-protégé relationship within the Trinamool Congress has evolved into one of the most intense political face-offs in recent Indian history.

From allies to adversaries

Once close colleagues in the TMC, Banerjee and Adhikari’s relationship changed dramatically when the latter switched to the Bharatiya Janata Party in 2020. The shift transformed him from a trusted lieutenant into her most formidable challenger.

Their shared political journey is closely tied to Nandigram — a region central to Bengal’s political transformation.

The Nandigram chapter

During the 2007 anti-land acquisition movement against the Left Front government, Adhikari emerged as a key organiser alongside Banerjee. The agitation played a crucial role in bringing the TMC to power in 2011, ending 34 years of Left rule.

Adhikari’s influence within the party grew rapidly. He held multiple ministerial roles and was widely seen as Banerjee’s organisational backbone in rural Bengal, particularly in East Midnapore. For years, he remained one of her closest aides.

However, cracks began to appear around 2019 amid internal tensions and allegations of sidelining. By 2020, Adhikari’s defection to the BJP marked a decisive break — and the beginning of a high-stakes rivalry.

2021: The turning point

The contest reached its peak during the 2021 Assembly elections when Banerjee chose to contest from Nandigram, Adhikari’s stronghold. In a closely fought battle, Adhikari defeated the sitting chief minister — a symbolic upset despite the TMC securing a statewide victory.

Following the loss, Banerjee briefly remained outside the विधानसभा until she won a bypoll from Bhabanipur. The result cemented Adhikari’s emergence as her principal rival.

Ongoing clashes

In the years since, the two leaders have repeatedly clashed over issues ranging from law and order to allegations of political violence and voter manipulation. In a recent flashpoint, the TMC demanded the removal of the returning officer for Bhabanipur, alleging proximity to Adhikari.

2026 elections: Round two

The rivalry has now entered a new phase in the 2026 Assembly elections. Adhikari has taken the battle directly to Banerjee’s home turf, contesting from Bhabanipur while also retaining his base in Nandigram.

Polling in West Bengal will be held in two phases — April 23 and April 29 — with counting scheduled for May 4 alongside elections in other states.

Banerjee has returned to her familiar campaign pitch, positioning herself as Bengal’s defender against what she calls external interference. Adhikari, on the other hand, is framing the election as a chance for political change, pointing to his 2021 victory as proof that her dominance can be challenged.

As the state heads to the polls, the contest once again centres on a relationship that reshaped Bengal’s political landscape — a leader and her former aide, now locked in a rivalry that continues to define its present and future.
