BJP's Bengal strategy goes far beyond poaching three TMC Rajya Sabha MPs. According to reports, the party is building parallel organisational cells inside TMC-controlled districts, cultivating second-rung leaders disenchanted with Mamata Banerjee's centralised command, and timing defections to fracture TMC's municipal election arithmetic before 2026 polls.

Three Rajya Sabha MPs resign from Trinamool Congress. The headlines land, the TV panels erupt, the cycle moves on. But here is the thing about a well-run destabilisation campaign: the resignations are never the operation — they are the press release. The operation is what happens two levels below, in the district committees and the municipal wards, where the cameras never go.

And that, according to a detailed report by Amar Ujala, is precisely where BJP's 'Operation TMC' is being waged in July 2026. Not in Parliament. Not on prime-time television. But in the laneways of TMC's own organisational map — the blocks, the districts, the municipal strongholds where Mamata Banerjee's party has ruled unchallenged for over a decade.

The Goa Model, Bengal Edition

If this playbook feels familiar, it should. BJP perfected it in Goa, where it didn't merely poach legislators — it built a shadow infrastructure inside the ruling party's districts first, then pulled the pillars out when the electoral math demanded it. The Bengal version, as Amar Ujala reports, follows an eerily similar sequence: identify disenchanted second-rung TMC leaders, offer them organisational backing through parallel BJP cells operating within the same districts, and wait for the right calendar moment to trigger the public defections.

The three Rajya Sabha resignations — including that of Ritabrata Banerjee, per the Amar Ujala report — were calibrated for maximum symbolic impact. A Rajya Sabha exit does not change floor numbers in the state assembly. What it does is far more valuable: it signals to every mid-level TMC functionary watching from a district headquarters that the door is open, that crossing over is safe, that the central leadership in Delhi is personally managing the landing.

Political Pulse

The talk inside Bengal's political corridors, according to those tracking the churn, is not about whether more defections will come — it is about how many. Whispers in party circles suggest that BJP's target list extends well beyond Rajya Sabha members into state-level legislators and, crucially, into the municipal leadership tier. The reasoning, those familiar with the strategy suggest, is ruthlessly simple: you do not need to win the assembly to cripple TMC. You need to win the municipalities.

Why municipalities? Because TMC's grassroots dominance — the ward-level networks that deliver votes, manage local patronage, and keep the party's ground game alive — runs through municipal bodies. Crack that layer open, and the assembly superstructure starts wobbling on its own. The timing is no accident either: West Bengal's municipal elections are the next major electoral test, and every ward councillor who switches sides takes a local machine with them.

India Herald's read of what is really driving this is the convergence of two forces BJP did not create but is expertly exploiting. The first is TMC's own organisational rot — a party that has run Bengal for over a decade with an increasingly centralised command structure under Mamata Banerjee, leaving district-level leaders feeling sidelined, unheard, and expendable. The second is the post-2024 national arithmetic: BJP needs Bengal seats to compensate for potential losses elsewhere in the next general election cycle, and building from the municipality up is cheaper, faster, and more durable than fighting Mamata head-on in assembly contests.

Can Mamata's Counter-Purge Actually Work?

Mamata Banerjee is not watching this passively. Reports indicate that TMC has responded with a two-pronged counter-strategy: expulsions of suspected BJP sympathisers within the party ranks, and a rally blitz designed to shore up grassroots morale. The logic is classic Mamata — fight fire with spectacle, show strength on the street, dare the fence-sitters to cross and face the consequences.

But there is a structural problem with the purge-and-rally approach that no amount of stage presence can fix. Every expulsion TMC conducts hands BJP a ready-made recruit — someone who now has a personal grievance, a local network, and nowhere to go except across the aisle. The purge, paradoxically, may be doing half of BJP's recruitment work for them. According to the Amar Ujala report, the parallel organisation-building strategy is designed precisely to absorb these expelled or disenchanted leaders, giving them an immediate institutional home inside BJP's Bengal apparatus.

The rally blitz faces a different mathematical reality. Mamata's rallies still draw massive crowds — that has never been in question. But rallies consolidate the already loyal; they do not address the mid-level functionary who has been passed over for a ticket three times, who watches a colleague cross over and get a BJP state vice-presidency, and who is quietly taking calls from someone in Delhi. That functionary is not attending the rally. He is attending a meeting in a parallel cell.

The 30-Day Window

The next month is where this either accelerates or stalls. If BJP can engineer another wave of visible defections — particularly from the municipal leadership tier — before the election commission's calendar forces a timeline on municipal polls, TMC faces the prospect of contesting local body elections with a fractured ground apparatus. If Mamata can stabilise the bleeding through a combination of genuine organisational reform (not just purges) and credible counter-offers to wavering leaders, she buys time.

But here is the question that should keep Kolkata's political class up at night: is the rot BJP is exploiting something they created, or something TMC built all by itself? Because if a party's mid-level leaders are this ready to leave — if the parallel cells find this much fertile ground — then the problem is not the poacher. The problem is the house that left its doors unlocked for a decade, confident nobody would dare walk in.

The next thirty days will not just determine a few more resignations. They will answer a more fundamental question about whether TMC's organisational model — built around one leader's personal authority — can survive the kind of systematic, patient, district-by-district erosion that BJP has now clearly committed to. Amit Shah does not run operations he intends to abandon. And Mamata Banerjee does not lose fights she sees coming. The collision is the story. Watch the municipalities.

Key Takeaways

• BJP's 'Operation TMC' extends far beyond three Rajya Sabha resignations — the core strategy, according to Amar Ujala, involves building parallel organisational cells inside TMC-controlled districts to erode grassroots dominance ahead of municipal elections.
• TMC's counter-strategy of expulsions and rally blitzes may be counterproductive: every purge hands BJP a ready-made recruit with a local network and a personal grievance, per the reported dynamics.
• The next 30 days are the critical window — if BJP triggers another defection wave from the municipal leadership tier before election commission timelines firm up, TMC could face local body polls with a fractured ground apparatus.
• The deeper vulnerability is structural: TMC's hyper-centralised command under Mamata Banerjee has left district-level leaders feeling sidelined — a condition BJP is exploiting, not creating.

Frequently Asked Questions

What is BJP's 'Operation TMC' in West Bengal?

According to Amar Ujala, 'Operation TMC' is BJP's multi-phase strategy to weaken Trinamool Congress through engineered defections of Rajya Sabha MPs, cultivation of parallel organisational cells inside TMC-controlled districts, and systematic targeting of municipal-level leaders — timed to disrupt TMC's ground apparatus before upcoming local body elections.

How many TMC MPs have resigned so far in 2026?

Three TMC Rajya Sabha MPs, including Ritabrata Banerjee, have resigned as part of the current phase of BJP's operation, according to Amar Ujala's reporting in July 2026.

Can Mamata Banerjee stop the TMC defections to BJP?

TMC has responded with expulsions and a rally blitz, but analysts and political observers note that each expulsion potentially hands BJP a ready-made recruit with a local network. The structural challenge is that TMC's hyper-centralised model has left district leaders feeling sidelined — a condition that makes counter-measures harder to sustain without genuine organisational reform, according to reports.

What is the 'Goa model' of defections BJP is reportedly using in Bengal?

The 'Goa model' refers to BJP's strategy of building shadow organisational infrastructure inside a ruling party's own districts before triggering visible defections at electorally optimal moments — a playbook BJP successfully used in Goa and is now reportedly adapting for West Bengal, according to political analysis.
