West Bengal Chief Minister Mamata Banerjee will intensify her offensive against the EC's Special Intensive Revision (SIR) of electoral rolls with rallies in Malda and Murshidabad this week, followed by a major mobilisation in Cooch Behar next week, TMC sources said.

This marks Ms. Banerjee's second phase of anti-SIR mobilisation after her Bongaon rally last week in the refugee-dominated Matua belt, where she alleged the revision drive was being misused to intimidate borderland families.

The TMC is positioning her district-wise campaign as a counter to the BJP's "infiltrator-cleansing" narrative.

The TMC leaders said the decision to hold consecutive rallies in Malda, Murshidabad on December 3, 4 and Cooch Behar on December 9, in three politically sensitive border districts with sizeable minority, migrant and displaced populations, signals a deliberate attempt to reclaim the narrative ahead of 2026, especially as the SIR exercise fuels unease over scrutiny of documents, identity and citizenship.

The Malda rally is scheduled at Gajole and Murshidabad's at Beharampore stadium.
