TMC Crisis Deepens in West Bengal: Mamata Faces a Fight to Rebuild the Party and Retain Its Political Identity

From a dominant force in Bengal politics to a party facing an internal revolt, leadership dispute and symbol battle, the Trinamool Congress is now confronting one of its most complicated organisational phases.

Kolkata: The political landscape of West Bengal has entered a new phase after the 2026 Assembly election, with the Trinamool Congress (TMC) facing an internal battle that has gone far beyond differences over leadership.

The party founded and led by Mamata Banerjee is now dealing with a rebellion within its ranks, competing claims over organisational control and an unprecedented dispute over the party’s official name and election symbol.

The Election Commission has temporarily frozen the All India Trinamool Congress name and the party’s traditional Flowers and Grass symbol for the upcoming by-elections. Both rival camps have been allotted separate temporary identities. The Mamata-led faction has been given the name Mamata All India Trinamool Congress with the Football Player symbol, while the rival camp has been allotted Democratic Trinamool Congress and the Envelope symbol.

The rebellion that changed the equation

The roots of the current crisis can be traced to the aftermath of the 2026 Assembly election.

In June, the internal division became public when a large group of TMC legislators backed rebel leader Ritabrata Banerjee for the post of Leader of the Opposition. Reports said that around 58 of the party’s 80 MLAs supported the move, bringing the organisational conflict directly into the state Assembly.

The rebellion subsequently moved from the legislature to the organisational structure of the party.

The rebel camp claimed control over the party’s organisational machinery and later projected senior MLA Arup Roy as its chairperson. Mamata’s loyalists, however, rejected the move and continued to recognise Banerjee as the party’s legitimate leader.

What initially appeared to be an internal leadership dispute therefore developed into a larger question:

Who actually controls the Trinamool Congress?

The battle is now over the party’s identity

The most striking development in the TMC dispute has been the intervention of the Election Commission.

With two rival groups claiming the same party identity, the Commission temporarily froze the original TMC name and the Flowers and Grass symbol for the by-elections. Both sides were asked to select alternative names and symbols.

The subsequent allocation of separate identities has made the dispute even more visible.

For the Mamata camp, the new temporary identity is Mamata All India Trinamool Congress, with a Football Player symbol.

The rival camp has been recognised for the by-election as Democratic Trinamool Congress, with an Envelope symbol.

The arrangements are interim and linked to the electoral contest while the larger dispute over control of the original party remains unresolved.

Mamata’s next challenge: bringing the rebels back

For Mamata Banerjee, the political challenge is now two-fold.

One part is to retain control over the organisation. The other is to prevent the internal split from permanently weakening the party’s grassroots structure.

If the rebel legislators and leaders are brought back into the mainstream, the move could help reduce the organisational divide. But reconciliation would also require addressing the questions that triggered the rebellion in the first place.

The issue is therefore not simply about numbers in the Assembly.

It is about leadership, organisational authority, political identity and the future direction of the party.

BJP’s rise has completely altered Bengal’s political landscape

The 2026 Assembly election also changed the broader political equation in West Bengal, with the BJP emerging as the governing force.

That has placed TMC in a new role in state politics and increased the importance of rebuilding its organisation after the electoral setback.

For years, TMC’s political strategy revolved around governing the state. It must now operate in an environment where organisational consolidation and opposition politics have become central to its future strategy.

At the same time, Mamata Banerjee has questioned the election process and alleged irregularities that she believes affected her party’s performance.

Those allegations remain politically contested and should be distinguished from independently established findings.

‘Vote theft’ allegations add another layer to the dispute

The controversy surrounding the 2026 election has also included allegations relating to electoral rolls and the voting process.

Opposition leaders have raised questions over alleged irregularities, while Mamata Banerjee has also made claims concerning voter-list deletions and alleged manipulation of the election process.

Such claims have become part of the wider political battle in Bengal. However, allegations made by political parties should not automatically be treated as established facts. Their evidentiary and legal status depends on official records, investigations and decisions by competent authorities.

This distinction is particularly important because the political battle inside TMC and the allegations concerning the electoral process are two separate issues.

The symbol dispute could have a wider political impact

Election symbols are not merely administrative identifiers in Indian politics. For established political parties, they are closely associated with their public identity and electoral recognition.

The temporary freezing of TMC’s traditional symbol therefore represents a significant organisational challenge for both factions.

The Election Commission’s interim arrangement allows both groups to contest the forthcoming by-elections under separate identities while the larger dispute continues.

The Supreme Court has also sought clarity from the Election Commission on the timeline for resolving the dispute over the TMC name and symbol, underscoring the legal significance of the matter ahead of the by-elections.

What lies ahead for Mamata and TMC?

The coming weeks could be important for determining the direction of the party.

Several questions remain open:

Will the rebel legislators return to Mamata Banerjee’s camp?

Will the two factions eventually reach an organisational settlement?

Who will ultimately retain the original TMC name and the Flowers and Grass symbol?

How will TMC rebuild its organisation after losing power in the state?

And what will be the political and legal outcome of the allegations surrounding the electoral process?

These questions are now closely connected.

A party fighting on multiple fronts

The TMC crisis is no longer just an argument between two groups of leaders.

It has developed into a multi-layered dispute involving leadership, legislators, organisational control, party identity, election symbols and legal proceedings.

For Mamata Banerjee, the immediate task is to keep the party’s organisational structure functioning while attempting to deal with the rebellion.

For the rebel camp, the challenge is to establish that it has sufficient organisational and political support to sustain its claim.

And for voters, the unfolding dispute raises a larger question about what happens when an established political party faces a formal split over its leadership and identity.

The bigger question for Bengal politics

West Bengal’s political landscape has changed significantly after the 2026 Assembly election.

The rise of the BJP to government, the TMC’s move into opposition, the internal rebellion and the dispute over the party’s name and symbol have created a political situation that is still evolving.

Whether this becomes a temporary organisational crisis or develops into a lasting realignment within Bengal politics will depend on future decisions by the rival factions, the Election Commission and the courts—as well as developments on the ground.

For Mamata Banerjee, the immediate battle is not only to challenge the new government—it is to determine whether the Trinamool Congress can emerge from its internal crisis as one organisation again.
