NEW DELHI: BJP Monday took a jibe at Mallikarjun Kharge, calling him an “accidental” Congress chief after he deflected questions on a possible leadership change in Karnataka.“Who exactly is this ‘unseen, unheard’ high command?” BJP MP Tejasvi Surya asked. “The Congress high command is like a ghost. It is unseen, unheard, but always felt. Even the Congress president, who people thought is the high command... says it’s not him.”Surya’s jab followed Kharge’s remark: “It is in the hands of the party high command. No one can say what is going on in the high command… they have the right to take further action…”
