Congress leader Shashi Tharoor said the party's quest to elect a new chief - its first non-Gandhi boss in over two decades - was off to a shaky start with the introduction of a pro-establishment candidate in his opponent, Mallikarjun Kharge. "There are some aspects that suggest an uneven playing field," he said at an NDTV townhall in Mumbai on Sunday, adding some leaders had told him they were "under pressure" to back Mr Kharge, seen as the choice of the Gandhis. But Mr Tharoor said the Gandhis remain neutral.
