"Her political survival depends on shielding a voter base created through fraudulent and illegal means," he charged, adding, "In 2026, West Bengal will elect a chief minister for the state, not someone who behaves as though she is the provincial leader of East Pakistan."

Malviya said India shares its international land borders with seven countries, stretching a total of about 15,106.7 km. The longest of these is the boundary with Bangladesh, extending 4,096.7 km, touching West Bengal, Assam, Meghalaya, Tripura, and Mizoram, he pointed out.

The BSF guards this entire stretch, yet West Bengal has witnessed the "highest levels of illegal infiltration", he claimed.

"The reason is clear: Mamata Banerjee's administration has repeatedly been accused of enabling this infiltration -- facilitating documentation, providing cover, and settling infiltrators in electorally strategic areas," the BJP leader added.

Malviya claimed the ruling TMC's mandate rests "heavily" on the seats it wins in the Kolkata Presidency region, which includes Kolkata, and parts of South and North 24 Parganas.

These are also the areas that have seen "maximum infiltration and the highest concentration of fake voters", he claimed.

"This region consistently witnesses widespread violence during elections, and the notorious Diamond Harbour is part of it," Madviya alleged.
