BJP chief Amit Shah on Tuesday tore into Trinamool Congress over its chief Mamata Banerjee’s ‘expiry PM’ jab ta Narendra Modi during a poll rally in West Bengal today. “Do you believe in India’s Constitution or not,” Shah said while attacking Banerjee. The comment was in response to the West Bengal Chief Minister’s reported comment that she doesn’t consider Narendra Modi as the Prime Minister of the country. Banerjee had reportedly refused to meet PM Modi for a review meeting over Cyclone ‘Fani’. Slamming Banerjee, Shah also added that, “it doesn’t matter what you think. (PM) Modi is coming back to power.”
