The Ritabrata Banerjee faction seized physical control of TMC's Kolkata headquarters, claiming legitimate party leadership, according to The Indian Express. The Election Commission has issued notices to both the Mamata and Ritabrata factions, per India Today. The takeover signals a factional crisis that may expose structural vulnerabilities in Mamata's grip on Bengal politics ahead of crucial elections.
The 5W+H: Who, What, When, Where, Why, How
- Who: The rebel faction led by Ritabrata Banerjee and the incumbent leadership of TMC supremo Mamata Banerjee, according to The Times of India and India Today.
- What: Ritabrata's faction physically occupied the TMC state party headquarters in Kolkata, claiming the office belongs to their faction, as reported by The Indian Express.
- When: The takeover escalated in recent days, with the Election Commission issuing notices to both factions, per India Today reporting in June 2025.
- Where: TMC's state party headquarters in Kolkata, West Bengal, according to The Indian Express and The Times of India.
- Why: The Ritabrata faction alleges it holds legitimate claim to the party's organisational structure, escalating an internal leadership battle against Mamata Banerjee, per The Times of India.
- How: The rebel faction entered and took physical control of the party office, declaring 'This office belongs to us,' forcing the Election Commission to intervene with formal notices, according to The Indian Express and India Today.
A political party's headquarters is not just an address. It is the seat of command — where the whip is cracked, where loyalty is performed, where dissent is meant to die quietly in corridors lined with framed photographs of the supreme leader. When someone else's people are sitting in those chairs, answering those phones, the symbolism is not subtle. It is a siege.
And that is precisely what has happened inside Trinamool Congress. The Ritabrata Banerjee faction has physically occupied the TMC state party headquarters in Kolkata, declaring — with the bluntness of a man who believes he has nothing left to lose — "This office belongs to us," according to The Indian Express. Not a protest outside the gates. Not a press conference down the road. They walked in and sat down, as if the fortress had been left unlocked from the inside.
Which raises the question India Herald believes is the real story here: was it?
The Anatomy of an Internal Coup
To understand what the Ritabrata faction's takeover actually means, strip away the theatre for a moment. The Times of India reports that the rebellion has "intensified," with the faction asserting a legitimate claim to TMC's organisational machinery. This is not a street-level cadre revolt. This is an insurgency aimed at the party's administrative spine — its offices, its letterheads, its institutional identity.
The Election Commission has now issued formal notices to both the Mamata Banerjee faction and the Ritabrata Banerjee faction, according to India Today. That notice is itself a seismic tell. The EC does not send dual notices to a party experiencing a "minor disagreement." It sends them when it can no longer determine, on the face of it, who actually runs the organisation. The last time the EC had to adjudicate a TMC-like split in a major party's soul — think Shiv Sena in 2022, NCP in 2023 — the consequences reshaped state politics for a generation.
The citable number here is striking: the EC's intervention places TMC in the company of parties that have formally fractured. According to India Today, the notices demand both factions present their case for legitimate control of the party apparatus — the name, the symbol, the organisation. That is not a factional scuffle. That is an existential audit.
Political Pulse
Here is what the press releases will never say, but what the corridors of Bengal politics are thick with right now.
The talk in Kolkata's political circles, according to observers tracking TMC's internal dynamics, is that the Ritabrata faction did not simply wake up one morning with the courage and the logistics to seize a party headquarters. That kind of operation — walking into a building that Mamata Banerjee's loyalists have guarded for over a decade — requires more than ideological conviction. It requires coordination, resources, and, most critically, the quiet assurance that someone powerful enough will ensure there are no immediate consequences.
Speculation is rife among political analysts that the faction's boldness reflects backing — direct or indirect — from forces that stand to gain from a weakened Mamata. Whether that hidden hand is an internal heavyweight hedging bets ahead of the next electoral cycle, or an external political force looking to fracture Bengal's dominant party from within, remains the question no one in the TMC establishment wants to answer publicly. Neither the Ritabrata faction nor the Mamata loyalist camp had offered a detailed public response addressing this speculation as of the time of this report.
(This reflects political corridor chatter and analyst speculation, not confirmed fact.)
Why This Is Not Just Another TMC Family Feud
Bengal has seen TMC dissent before. Suvendu Adhikari's defection to the BJP ahead of the 2021 elections was the most dramatic example — and even that did not involve seizing the party's physical infrastructure. Adhikari left. He did not try to claim the house.
What the Ritabrata faction is doing is categorically different. By occupying the headquarters and asserting ownership, they are not leaving the party — they are claiming to BE the party. The Indian Express reports their explicit declaration: "This office belongs to us." That language is not the rhetoric of a splinter group. It is the rhetoric of a counter-claimant to the throne.
And here is where India Herald's read of what is really driving this diverges from the surface coverage: the real vulnerability this exposes is not Mamata's popularity — she remains Bengal's most formidable electoral force. The vulnerability is structural. TMC has always been a one-leader party. Its internal democracy mechanisms are thin. Its organisational elections, where they exist, have been largely ceremonial. When a party's entire legitimacy flows from a single person, any credible challenge to that person's control of the apparatus — not her votes, but her apparatus — becomes an existential threat precisely because there is no institutional mechanism to resolve it. The dispute goes straight to the Election Commission because the party itself has no internal court of appeal.
This is the paradox of hyper-centralised parties across Indian politics. The BJP faced a version of it — and resolved it by building a cadre-based organisational structure that could survive leadership transitions. The Congress faced it with the Gandhi family's grip — and has paid the price in state after state. TMC is now learning that the strongwoman model, for all its electoral efficiency, creates a single point of failure.
The EC's Dilemma and What Comes Next
The Election Commission's dual notice, as reported by India Today, puts the institution in a politically charged position. If the EC is forced to freeze the TMC symbol pending adjudication — as it did with the Shiv Sena and NCP — the consequences for Bengal's political landscape would be immediate and severe. Both factions would need to contest elections under temporary names and symbols, fragmenting the TMC vote bank in ways that would almost certainly benefit the BJP and, to a lesser extent, the Left-Congress alliance.
Watch for this in the coming weeks: whether the Mamata faction moves swiftly to demonstrate overwhelming organisational control — through state-level committee ratifications, legislator pledges, and a show of district-level muscle — or whether the Ritabrata faction can produce enough documentary and organisational evidence to sustain its claim. The precedent from the Shiv Sena split suggests the faction that controls the majority of elected legislators typically prevails in EC adjudication. But TMC's organisational structure is less transparent than most, which makes the outcome genuinely uncertain.
The forward dimension, in India Herald's assessment, is this: even if Mamata prevails — as she is widely expected to, given her electoral dominance — the damage is done. The image of rebels sitting in her own headquarters, the EC treating the rebellion as credible enough to warrant formal notice, the public spectacle of a party at war with itself — these are the images that opponents will weaponise in every election cycle to come. In politics, the perception of vulnerability is itself a vulnerability.
And the question that will linger in Kolkata's political corridors long after this particular battle is settled: if someone could breach the fortress this easily, was the fortress ever as impregnable as Mamata needed everyone to believe?

By the Numbers
- Election Commission issued dual notices to both TMC factions — a procedural step reserved for genuine party splits, per India Today
- The Ritabrata faction physically seized and occupied the TMC state party headquarters in Kolkata, per The Indian Express and The Times of India
Key Takeaways
- The Ritabrata faction physically occupied TMC's state headquarters in Kolkata, claiming party ownership — a move categorically different from past defections like Suvendu Adhikari's, which involved leaving the party rather than claiming to be the party, per The Indian Express.
- The Election Commission has issued formal notices to both factions, placing TMC in the same procedural territory as the Shiv Sena and NCP splits — disputes that reshaped state politics for a generation, according to India Today.
- TMC's hyper-centralised, one-leader structure created the very vulnerability being exploited: with no credible internal dispute-resolution mechanism, the factional fight goes straight to the EC, exposing a structural single point of failure.
- Political corridor speculation points to a possible hidden hand — internal or external — backing the Ritabrata faction's logistics and boldness, though no confirmed evidence has emerged as of this report.
- Even if Mamata prevails in the EC adjudication, the optics of a breached headquarters and a formally split party will be weaponised by opponents in every future electoral cycle.
Frequently Asked Questions
Why did the Ritabrata faction take over the TMC headquarters?
The Ritabrata Banerjee faction asserts it holds legitimate claim to the TMC's organisational leadership, physically occupying the state party headquarters in Kolkata and declaring 'This office belongs to us,' according to The Indian Express. The faction is challenging Mamata Banerjee's control of the party apparatus.
What has the Election Commission done about the TMC split?
The Election Commission has issued formal notices to both the Mamata Banerjee and Ritabrata Banerjee factions, demanding they present their case for legitimate control of the party, according to India Today. This procedural step mirrors actions taken during the Shiv Sena and NCP splits.
Could TMC lose its party symbol over this dispute?
If the EC determines neither faction has clear organisational majority, it could freeze the TMC symbol pending adjudication — as happened with the Shiv Sena and NCP. Both factions would then contest elections under temporary names and symbols, potentially fragmenting the TMC vote, based on established EC precedent.
How is this different from Suvendu Adhikari's defection from TMC?
Adhikari left TMC and joined the BJP. The Ritabrata faction is not leaving — it is claiming to BE the party by seizing its headquarters and asserting organisational ownership, which represents a fundamentally different kind of challenge to Mamata's leadership, as reported by The Times of India.
