Former West Bengal Chief Minister Mamata Banerjee on Saturday, 7 November 2026, threatened to approach the Supreme Court over clashes allegedly involving Bharatiya Janata Party (BJP) and Mamata All India Trinamool Congress (MAITC) supporters outside the south Kolkata residence of her nephew, Abhishek Banerjee. Speaking to reporters after visiting Abhishek's home in Kalighat, she accused the BJP and the police of conspiring to foment tension in the neighbourhood.

What Happened Outside Abhishek's Residence

According to Mamata, a group she described as 'lumpen elements backed by the BJP' attacked Abhishek's house after 2 a.m. on Saturday while police allegedly stood by as passive observers. Abhishek Banerjee is the Trinamool Congress's Lok Sabha member from Diamond Harbour. The two residences — Abhishek's and Mamata's — are located in the same south Kolkata neighbourhood, in close proximity to each other.

Police Singled Out, SC Warning Issued

Mamata specifically named Bolai Bag, officer-in-charge of Kalighat police station, which has jurisdiction over both residences, warning that his conduct risked triggering public anger. She said she would escalate the matter to the highest judicial level if the situation was not addressed. 'The police remained silent spectators,' she alleged, characterising the inaction as deliberate.

Kali Puja Disruption Alleged

Beyond the overnight clashes, Mamata also accused the police of attempting to disrupt the annual Kali Puja celebrations organised at her own residence. She alleged that prohibitory orders under Section 163 of the BNSS, 2023 had been invoked, police vehicles had been positioned to block the entrance to her home, and surveillance had been intensified to prevent gatherings during the festival. 'An atmosphere of unrest has been deliberately created in this area before the Kali Puja. The pujas of old clubs are being prevented. However, new pujas are starting overnight,' she said, adding that the cumulative effect was to stop residents from visiting her home for the occasion.

Administration and BJP in the Crosshairs

Mamata stopped short of naming the sitting Chief Minister directly but made an unmistakable reference to Suvendu Adhikari when she said: 'The one who is leading the administration in West Bengal is behind all these.' She also drew a sharp contrast between the BJP's stated political messaging and its alleged on-ground conduct. 'On one hand, they are organising ‘Save Democracy, Eliminate Anarchy’ rallies in the state, and on the other hand, they are the ones who are trampling the democratic structure,' she said. She clarified she was not indicting every BJP member, but pointed firmly at the party's state leadership.

Context and What Comes Next

The incident comes at a charged moment in West Bengal politics, with the Trinamool Congress and the BJP locked in intensifying rivalry ahead of local body elections. Clashes around politically significant residences — particularly during major religious festivals — have been a recurring feature of the state's political landscape. Mamata's Supreme Court threat raises the stakes considerably; a formal petition, if filed, would draw national judicial scrutiny onto the state's law-and-order machinery. All eyes are now on whether the court is formally approached and how the state administration responds to the allegations.
