Prime Minister Narendra Modi, engaged in a pitched battle with Mamata Banerjee over violence at Amit Shah's rally, taunted the Bengal Chief Minister today, saying he wanted to see if she would allow his rally in Kolkata today. The rallies of senior BJP leaders -- including Amit Shah and the party's star campaigner Yogi Adityanath -- have been a flashpoint in the Trinamool-ruled state, where the BJP is aiming to win 23 of 42 seats.
