Union Minister Ravi Shankar Prasad on Wednesday said Prime Minister Narendra Modi as pure as the Ganga, adding that the corruption allegations against PM Modi are baseless, false, shameful and mala fide and they reflected Rahul Gandhi’s frustration in leading his party to disastrous defeats in state after state.Prasad said the Congress is trying to divert attention from alleged involvement of Gandhi family and other senior Congress leaders in numerous scams, including the AgustaWestland.
