Union Home Minister Amit Shah welcomed high-profile Trinamool Congress rebel Suvendu Adhikari and a number of others to the BJP on Saturday at a mega rally in West Bengal's Midnapore, sparing no shot at Chief Minister Mamata Banerjee.

By the time elections come, you will be left all alone," he said.
