With Lok Sabha polls around the corner, Priyanka Gandhi Vadra has become the latest entrant from the Gandhi family to take the big leap of joining politics. Priyanka Gandhi had till now confined her role in politics to the constituencies of her brother Rahul Gandhi and mother Sonia Gandhi. Dubbed as Congress' 'Brahmastra', Priyanka Gandhi will debut as the General Secretary in charge of Eastern Uttar Pradesh pitching her against BJP heavyweights PM Narendra Modi and UP Chief Minister Yogi Adityanath. With the BJP shrugging the Congress' announcement, will the move play out as a game-changer or a gamble for the Congress?
