BJP's claim of "400 paar" is a joke, "300 paar" impossible and even "200 paar" may be a challenge in Lok Sabha polls, Congress leader Shashi Tharoor said, adding that BJP's loss is a "foregone conclusion". "BJP will draw a blank in Kerala, Tamil Nadu and Andhra Pradesh, and will do worse than its 2019 performance in South," Tharoor added.
