The war of words between Bharatiya Janta Party (BJP) and Congress has gone to the next level in the poll-bound state of Karnataka. In a scathing attack directed at Prime Minister Narendra Modi, Chief Minister Siddaramaiah called him the "most corrupt PM" and questioned how could Nirav Modi escape without PM Modi's knowledge when both of them were in Davos together. Congress leader's rant came a day after PM Modi's Mysuru rally where he criticised Karnataka government and made corruption remarks on its leaders.
