The Abhishek conundrum: Can Mamata Banerjee keep TMC united?

For nearly three decades, the Trinamool Congress (TMC) has been synonymous with Mamata Banerjee. She built the party from scratch, challenged the seemingly invincible Left Front, and emerged as Bengal's most formidable political force. Today, however, her greatest challenge is not posed by the BJP or the Left-Congress alliance, but by the party she built.

And, at the centre of the storm is her nephew, Abhishek Banerjee.

Mamata first rose to national prominence in 1984 when she defeated veteran CPI(M) leader Somnath Chatterjee in Jadavpur, earning a reputation as a giant killer. In 1998, she broke away from the Congress to form the TMC, a party built almost entirely around her political energy and mass appeal. Singur and Nandigram transformed the party's fortunes. Opposition to land acquisition for the Tata Motors Nano project and a proposed chemical hub evolved into a statewide movement against the Left Front under the slogan "Maa, Mati, Manush".

By 2011, Mamata had achieved what once seemed impossible – ending the Left Front's 34-year rule in West Bengal. Welfare initiatives such as Kanyashree, Sabooj Sathi and Lakshmir Bhandar helped consolidate support among women, rural households and economically weaker sections, reinforcing her image as a leader closely connected to the state's social realities.

Yet even as the TMC consolidated power, the foundations of a future succession struggle were quietly being laid.

Rising influence

The turning point came in 2014. After becoming MP from Diamond Harbour, Abhishek Banerjee steadily emerged as one of the most influential figures within the party. Supporters hailed the "Diamond Harbour model" as evidence of his political acumen, pointing to efficient welfare delivery, organisational discipline and relentless voter outreach. Within the party, a younger generation increasingly viewed him as the face of the future.

For Mamata Banerjee, Abhishek represented more than familial continuity. He embodied generational renewal. Articulate, media-savvy and organisationally focused, he appeared well positioned to modernise the party while preserving its electoral dominance. His rise reflected not merely family ties but also a conscious effort to prepare the TMC for a post-Mamata era.

Not everyone within the party, however, viewed his ascent in the same light.

As Abhishek's influence expanded, candidate selection, campaign management and strategic decision-making increasingly came under the control of a smaller inner circle. Political scientist Professor Maidul Islam believes the roots of today's crisis lie in this period.

"The TMC was built around Mamata Banerjee's mass movement, not a disciplined ideological cadre. As long as the party kept winning, its internal contradictions remained hidden. But increasing centralisation widened the gap between the leadership and the grassroots. The 2026 defeat merely exposed tensions that had been building for years," Islam said.

The first major rupture came with the departure of Mukul Roy in 2017, followed by Suvendu Adhikari in 2020. Both exits strengthened the perception that independent power centres within the party were finding it increasingly difficult to survive.

Internal fractures

Meanwhile, a series of controversies began eroding the moral authority that had powered Mamata's rise. The Park Street and Kamduni rape cases, the Saradha chit fund scam and the Narada sting operation all damaged the party's image. The most serious blow came with the school recruitment scam, where allegations that teaching and non-teaching jobs had been sold for cash struck at the credibility of public institutions and weakened public trust in the government.

The 2024 R.G. Kar Medical College and Hospital rape and murder case intensified public anger further, triggering protests on a scale not seen in Bengal since the Singur and Nandigram movements.

Corruption allegations, anti-incumbency, organisational fatigue and questions over succession had all begun weighing in on the party.

The setback in the 2026 assembly election brought those concerns into sharp focus.

Years of investigations and the arrests of ministers and senior leaders had already weakened the TMC's organisational machinery. After the defeat, several MLAs and MPs openly questioned Abhishek's leadership, blaming excessive centralisation, weakening grassroots engagement and the diminishing role of senior leaders in decision-making.

A dissident bloc led by Ritabrata Banerjee challenged the leadership, signalling that sections of the party were prepared to openly question a power structure that had gone largely unchallenged for years.

Discontent surfaced in Parliament as well. Four-time MP Kakoli Ghosh Dastidar publicly expressed dissatisfaction over her removal from key parliamentary responsibilities. Anubrata Mondal also questioned past leadership decisions, adding to the sense that internal differences were no longer being confined to closed-door discussions.

The sharpest challenge came from Kalyan Banerjee, whose reported ultimatum—"Either Abhishek or me"—reflected the frustration of leaders who felt increasingly sidelined.

Yet the rebellion is notable for one reason.

It is not directed at Mamata.

Defining choice

Despite the electoral setback and the public criticism, most dissidents continue to recognise Mamata as the party's unquestioned leader. Their complaint is not with her, but with the concentration of authority around Abhishek and a small circle of his trusted advisers.

Islam believes the roots of the conflict run deeper than individual personalities. “The TMC gradually shifted from a political movement to a tightly managed organisation. Centralised decision-making weakened local leadership, widened the gap between the grassroots and the top brass. What we are seeing today is the release of pressures that have been building inside the party for years.”

It leaves Mamata confronting, perhaps, the most difficult decision of her political life.

Standing firmly behind her nephew risks alienating senior leaders already unhappy with the party's direction. Distancing herself from him could weaken a succession plan that has been taking shape for more than a decade.

Political analyst Professor Subhamoy Maitra believes the challenge extends beyond the question of who succeeds Mamata. “A dynastic transition becomes far harder when a party is also battling questions of credibility. Corruption allegations, criminalisation and succession pressures can erode the foundations of a leader-centric party. The TMC is confronting all three at once.

“The real question is whether the TMC can outlive Mamata Banerjee. Unlike parties rooted in a strong ideological tradition, it has largely revolved around her leadership. Every regional party eventually faces a succession test. The challenge is whether organisational authority can become political legitimacy,” Maitra added.

That question carries particular significance in Bengal, where political legitimacy has historically been earned through agitation, mass mobilisation and electoral struggle—not inherited through family lineage.

The issue is no longer simply whether Abhishek can lead the party. It is whether he can command the authority that Mamata earned through decades of political struggle and repeated electoral battles.

Few politicians in contemporary India have demonstrated Mamata's capacity for political survival. Time and again, she has overcome crises, defeated opponents and proved predictions of her decline wrong.

But this challenge is different.

For the first time since the TMC was founded, the greatest threat to the party is not coming from an opponent outside its ranks. It is coming from uncertainty over what happens after Mamata.

The Abhishek question is no longer merely about succession. It is about whether Mamata can hold the flock together, and whether the TMC can manage its first real transition of power while preserving the political identity that made it Bengal's dominant force.
