Kolkata/IBNS: Union Home Minister Amit Shah on Wednesday targeted West Bengal Chief Minister Mamata Banerjee on infiltration ahead of the kickstarting of the Lok Sabha elections.

Addressing a rally in West Bengal's North Dinajpur, Shah said Mamata will not stop infiltration for her alleged vote bank politics.

"Mamata Didi will not stop infiltration because these infiltrators are her vote bank. PM Narendra Modi and the BJP government can stop infiltration in Bengal. We stopped infiltration in Assam," Shah said.

Shah, the top leader of the Bharatiya Janata Party (BJP), has urged people to help the saffron party bag at least 30 of 42 Lok Sabha seats in the state, which is dominated by Mamata's Trinamool Congress (TMC) for the last 15 years.

"I have come to tell you about Modi's guarantee... make us cross 30 seats, and form a BJP government in Bengal, we will stop infiltration," Shah said, hoping the BJP to improve its best performance in the state, i.e., 18 Lok Sabha seats in 2019.

Meanwhile, Mamata Banerjee has been countering the BJP on CAA, which aims to give citizenship to people from Pakistan, Bangladesh and Afghanistan who came to India due to religious persecution before 2015.

Countering BJP's claim, Mamata Banerjee has been saying registering for CAA will lead to losing of citizenship.

"Do not register for CAA. If you do, you will be a foreign and later you will be kept in detention camps. We all are citizens," she said.

In the 2019 Lok Sabha elections, the TMC suffered a setback by getting its tally down from 34 to 22 while the BJP got a meteoric rise from 2 to 18 seats.

However, BJP's hope to form government was dashed two years later when Mamata stormed back to power with over 200 assembly seats.
