Crisis in Mamata's TMC leaves Bengal’s Opposition politics at a crossroads

Me or Abhishek: Kalyan’s ultimatum

TMC MLAs have rebelled. MPs have revolted. Senior leaders have openly questioned the leadership. Even Kalyan Banerjee, who was among Mamata Banerjee's most loyal political associates for over two decades, has publicly targeted Abhishek Banerjee on Thursday (June 11).

What remains uncertain is where the rebellion will eventually lead, with competing claims, shifting loyalties and multiple political options still in play.

"I am with Mamata Banerjee. But Mamata has to decide whether she will keep Abhishek or me," Kalyan said, further exposing the fissures within the party.

His remark underlined the depth of the crisis confronting the party. Yet beneath the dissent lies a more complicated political reality.

What remains uncertain is whether the rebellion represents the birth of a new political formation or is merely another round of Bengal's familiar politics of migration towards power.

Does Bengal have a strong Opposition?

Yet the significance of the current turmoil extends beyond the fate of the TMC.

The party's defeat has reopened questions about the future of opposition politics in Bengal at a time when the state's polity is adjusting to its first change of government since 2011.

The TMC's crisis has created uncertainty not only about who will lead the opposition to the BJP government, but also about what kind of opposition Bengal will have in the years ahead.

What remains uncertain is where the rebellion will eventually lead, with competing claims, shifting loyalties and multiple political options still in play.

Is a split in the offing?

The rebels claim support from over 60 MLAs and between 19 and 20 of the party's 28 Lok Sabha MPs. On paper, those numbers would make this one of the most consequential splits in state politics. But the evidence remains incomplete.

The dissident camp has not publicly produced a letter carrying the signatures of all those MPs before the Lok Sabha speaker. The absence of such a letter matters because parliamentary recognition is determined by documents, not political claims.

Several names repeatedly circulated as members of the rebel camp have further complicated the narrative. Asansol MP Shatrughan Sinha publicly rejected suggestions that he was preparing to abandon Mamata Banerjee.

"I will not leave Mamata Banerjee in her difficult time," Sinha said, recalling how she stood by him during difficult phases of his own political career.

He went further, arguing that despite the defeat, Mamata still commands a substantial social base in Bengal.

Ideological emptiness of rebellion

Similar uncertainty extends to the assembly. The speaker's decision to recognise expelled leader Ritabrata Banerjee as Leader of the Opposition has itself become the subject of legal scrutiny before the Calcutta High Court. If the very status of the opposition leadership remains under challenge, it shows how fluid the situation remains.

What is striking, however, is not merely the scale of the rebellion but its ideological emptiness.

The rebels have levelled a range of allegations against Abhishek. They accuse him of centralising authority, sidelining veterans, and reducing the influence of district-level leadership. Some complain about organisational arrogance. Others argue that the party lost touch with its grassroots.

TMC consumed by politics that built it

But beyond opposition to Abhishek, what exactly is their political agenda?

Most of these leaders spent years defending the same organisation they now condemn. Many were beneficiaries of the very system they now describe as flawed. Their criticism, therefore, often appears driven more by political opportunism than by ideology.

That points to a broader reality of Bengal politics.

For years, politics in the state has revolved around access to power rather than ideological conviction. The TMC itself was a beneficiary of large-scale defections from both Congress and the Left. Many of today's rebels are products of that political culture.

The irony is that the same politics may now be consuming the TMC.

This ideological ambiguity may ultimately prove to be the rebellion's greatest weakness.

Bengal’s complex political transition

A rebellion built primarily around leadership disputes may attract legislators, but it is far less certain that it can attract voters.

The TMC may have suffered a decisive defeat, but it still secured more than 40 per cent of the vote.

TMC's electoral base, though diminished, remains substantial enough to leave a few political options open to its leadership despite the rebellion.

There is little doubt that corruption allegations, recruitment scandals, cut-money accusations and a culture of political intimidation severely damaged the party. Those factors contributed significantly to its defeat.

At the same time, the post-election spectacle of TMC leaders being pelted with eggs, chased from public meetings and greeted with chants of "chor, chor" has raised questions about whether all expressions of anger are entirely spontaneous.

The visible reluctance of authorities to intervene in some of these incidents has added to those questions.

This does not negate public resentment. It merely suggests that Bengal's political transition may be more complex than a simple uprising against a discredited regime.

Uncertain future

The scale of the defeat has, in some quarters, created an impression that the TMC has become politically irrelevant. The numbers suggest otherwise. More than four out of every 10 voters continued to support the party despite years of anti-incumbency, corruption allegations and organisational fatigue.

The party's electoral base, though diminished, remains substantial enough to leave a few political options open to its leadership despite the rebellion.

Meanwhile, Mamata Banerjee herself has revealed little about her future strategy.

Speculation about a possible merger between the TMC and Congress briefly dominated political discussion after meetings between senior leaders of both parties. Those reports were subsequently dismissed by Congress leadership, with Jairam Ramesh clarifying that discussions were confined to coordination within the INDIA Bloc rather than organisational integration.

The TMC too avoided endorsing merger speculation.

BJP leaders wary of TMC rebels

The state’s new BJP government is the immediate beneficiary of the confusion and disarray within the opposition camp.

But the long-term picture is less straightforward.

A growing number of BJP leaders have privately and publicly expressed discomfort with the increasing proximity between sections of the rebel TMC camp and the BJP.

Former governor and state BJP president Tathagata Roy on Thursday voiced his opposition to any rapprochement with certain TMC leaders, publicly urging Prime Minister Narendra Modi and Home Minister Amit Shah to avoid engagement with TMC MP Saayoni Ghosh while citing her past controversies.

Whether the BJP can forge closer ties with large sections of the TMC without creating tensions within its own organisation remains an open question.

Similar concerns have surfaced from leaders such as Arjun Singh, who earlier this week demanded arrest of TMC’s rebel MP Partha Bhaumik for his alleged involvement in post-poll violence after 2021 elections.

Many of the TMC leaders now reportedly seeking proximity to the BJP are the same individuals whom BJP workers spent years accusing of corruption, intimidation and abuse of power.

Welcoming them may strengthen the BJP in the short term. It could also generate resentment among grassroots workers who fought against them for years.

In that sense, the BJP risks inheriting some of the same malaise that weakened the TMC.

Can Left, Cong rise to the occasion?

In the short term, the ruling party may gain by weakening its principal challenger. Over time, however, it could blur distinctions between the BJP and the political culture it criticised before coming to the power.

Whether the BJP can forge closer ties with large sections of the TMC without creating tensions within its own organisation remains an open question.

This could create opportunities for forces outside the TMC-BJP binary.

Despite improved visibility during the election campaign, the Left remains electorally weak. Congress, too, continues to lack the organisational strength required to emerge as the principal opposition force.

Both parties therefore face a paradox. They stand to benefit from a weakened TMC, yet neither currently appears capable of independently occupying the political space that the TMC might vacate.

For that reason, the future of opposition politics in Bengal may depend not only on whether the TMC survives, but also on whether the Left and Congress can reinvent themselves.
