In West Bengal, the Bharatiya Janata Party (BJP) is focusing its campaign on national security, particularly concerning the Siliguri Corridor, also known as Chicken's Neck, which connects the northeastern states to the rest of India. Prime Minister Narendra Modi and other leaders have emphasized the importance of this region for national security, citing concerns over infiltration from Bangladesh. Modi accused the Trinamool Congress of neglecting security responsibilities and facilitating infiltration for political gain. The BJP asserts that a significant portion of the 4,000-kilometer border with Bangladesh remains unfenced due to the state government's refusal to allocate land for fencing. BJP leaders claim that within 45 days of coming to power, they will initiate border fencing to curb infiltration. They argue that local sentiment is shifting in their favor regarding these security issues. In contrast, the Trinamool Congress argues that border security is primarily the responsibility of the Union government and accuses the BJP of deflecting blame for its own failures. BJP representatives claim that significant development projects are underway in the region, while the Trinamool asserts its commitment to North Bengal's development.
