Union Home Minister Amit Shah on Saturday attacked the Mamata Banerjee-led Trinamool Congress government in West Bengal and said that by the time the election comes, the Chief Minister would be left all alone in her party.

"By the time elections come, you will be left all alone...Why are so many people leaving Trinamool Congress now? Because of the misrule, corruption and nepotism of Mamata Banerjee," Shah said at his mega rally.
