West Bengal BJP chief Samik Bhattacharya slammed ex-CM Mamata Banerjee over her support for Cockroach Janta Party (CJP). "Never heard of a 'lioness' going to a cockroach...Banerjee used to call herself a lioness," Bhattacharya said. "Her condition has become so bad that she has to go to a cockroach," he stated, adding that Banerjee "wanted to oust" BJP from Centre.
