West Bengal's Asansol Lok Sabha seat is a high-stake battleground for the Trinamool Congress and the BJP. The Trinamool has fielded its star campaigner and MP Shatrughan Sinha, while the BJP has fielded former Union Minister SS Ahluwalia against the actor-turned politician. "Nitish Kumar has lost credibility. I was part of the BJP's golden era," Mr Sinha told NDTV, adding the NDA will not cross the 220 mark in the general elections.
