Purulia: Amid the heated battle between political leaders in the ongoing Lok Sabha elections, Prime Minister Narendra Modi hit back at West Bengal Chief Minister Mamata Banerjee's 'slap of democracy' jibe and said the slap will become a blessing for him.

Addressing  an election rally at West Bengal's Purulia on Thursday, PM Modi retorted to the TMC supremo', who had recently said that whenever she sees him, she feels like giving him a tight slap of democracy.

"I was told that Didi has told you that she feels like slapping Modi. Mamata Didi, I call you Didi and your slap will become a blessing for me," said Modi in Purulia where Mamata had made the remark on Tuesday.

At a public meeting in Purulia, Mamata had said that Narendra Modi deserved the slap for accusing her party , the Trinmool Congress, of using extortion money. She also drew a parallel between the prime minister and Duryodhana, Dushayasana and Raavana.

On Thursday, Modi said, "But Didi had you shown the courage to slap those friends of yours, who looted the money of poor people through chit funds, you wouldn't be so scared today."

The Prime Minister also raked up the issue of Bangladeshi immigrants. He said, "I want to assure you that the infiltrators that Didi and Trinamool have made their cadre, will be identified. Those who trouble our daughters and the cultured Bengalis here, they will be identified."
