BJP MP Sambit Patra took a dig at the ongoing tussle in the Karnataka Congress over the change of CM. "In Karnataka, the game 'Kaun banega Mukhyamantri' (Who'll become CM) is going on," Patra said. His remarks came hours after Deputy CM DK Shivakumar said he and CM Siddaramaiah would travel to Delhi if asked by the party high command.
