Amid the prevailing tension in the wake of the hijacking of the Indian Airlines plane to Kandahar in 1999, Mamata Banerjee, a Union Cabinet Minister then, had offered herself as a hostage in exchange for the passengers of the flight, former Finance Minister Yashwant Sinha said today. Recalling his days with her as a colleague, the former senior BJP leader said the Trinamool chief has been a "fighter" right from the beginning. He joined her party today in Kolkata, having quit the BJP in 2018.
