By West Bengal politics is witnessing a major organisational dispute within the Trinamool Congress (TMC), with the Election Commission of India (ECI) scheduled to hear rival factions over the party’s organisational control, name and election symbol on September 17, 2026.
The development comes just weeks before the October 6 Assembly by-elections in Nandigram and Rejinagar. Both factions have fielded candidates in the upcoming bypolls, making the ECI proceedings particularly significant for the party’s electoral identity.
What Is the TMC Dispute About?
The dispute concerns competing claims over the organisational control of the All India Trinamool Congress, including the party’s recognised name and its election symbol.
One faction is led by Mamata Banerjee, while the rival group is led by West Bengal Leader of Opposition Ritabrata Banerjee. Both sides have submitted documents and representations to the Election Commission regarding their respective claims.
The ECI has been examining documents submitted by both sides before deciding on the matter.
Why Is September 17 Important?
The Election Commission has scheduled hearings with representatives of the rival factions on September 17 in New Delhi.
A five-member delegation led by Ritabrata Banerjee is scheduled to appear at 3 PM at Nirvachan Sadan on Ashoka Road. Reports also indicate that the Mamata Banerjee-led faction has been called for a separate hearing later in the day.
The hearings follow an earlier interaction between the rival groups and the poll panel on September 12.
What Has the Election Commission Asked For?
The ECI has sought additional information and documents from the competing groups as part of its examination of the dispute.
The Mamata-led faction was given time to submit additional documents by September 16. The commission had indicated that another hearing could be held on September 17 after reviewing the submissions.
The documents relate to the organisational structure of the party and the claims being made by the two groups.
What About the TMC Election Symbol?
The election symbol is one of the central issues in the dispute.
The rival groups are both seeking recognition as the legitimate TMC and are contesting the question of who is entitled to use the party’s recognised symbol.
The issue has become particularly urgent because nominations for the upcoming West Bengal bypolls closed on September 16, while the ECI had not yet issued a final decision on the dispute.
Why Are Nandigram and Rejinagar Important?
The upcoming by-elections in Nandigram and Rejinagar are scheduled for October 6, 2026.
Both TMC factions have announced candidates for the two constituencies. This means the party-identity dispute is unfolding directly alongside an electoral contest.
Nandigram has additional political significance because of its history in West Bengal politics and the prominent political figures associated with the constituency.
Rejinagar is also heading into a multi-party contest, adding another dimension to the by-election campaign.
What Happens If the Dispute Remains Unresolved?
The Election Commission will determine how the competing claims should be handled under the applicable election rules.
Until the commission reaches a decision, questions remain about how the rival groups will be identified for electoral purposes and how the party’s recognised identity and symbol will be treated during the bypoll process.
Reports have discussed various possible administrative outcomes, but these should not be treated as confirmed until the ECI formally announces its decision.
Political Background
The dispute comes after major changes in West Bengal’s political landscape following the 2026 Assembly elections.
The rival TMC groups are now seeking recognition and organisational legitimacy, while the upcoming bypolls provide an immediate electoral setting in which their competing claims could be tested.
The Election Commission’s role is therefore focused on the formal recognition and electoral identity of the party rather than determining which political faction has greater public support.
What Should Voters Watch?
For voters in Nandigram and Rejinagar, the immediate issues to watch include:
- The ECI’s decision regarding the TMC name and symbol.
- How candidates from the competing factions are identified on the ballot.
- Any changes to the electoral symbols assigned to the factions.
- Campaign developments ahead of the October 6 bypolls.
- Official instructions issued by the Election Commission.
The ECI’s formal announcements will be the key source for confirming any change in party recognition or symbol allocation.
What Happens Next?
The September 17 hearings are expected to give both sides an opportunity to present their respective positions before the Election Commission.
The commission will consider the submissions and documents before taking further action. The final outcome will have direct implications for the upcoming West Bengal by-elections because both factions have already entered the electoral contest.
The October 6 Nandigram and Rejinagar bypolls will therefore take place against the backdrop of an unresolved organisational dispute within the TMC.
Conclusion
West Bengal politics is entering an important phase as the Election Commission examines competing claims over the Trinamool Congress’s organisational control, party name and election symbol.
With rival factions preparing for the October 6 bypolls in Nandigram and Rejinagar, the ECI’s proceedings on September 17 are being closely watched.
The immediate focus is on the commission’s formal process and any official order that follows. Until such an order is issued, claims about the final status of the party name or symbol remain unresolved.
For voters and political observers, the next key development will be the Election Commission’s official decision and its impact on the upcoming by-elections.
