Shiv Sena (UBT) MP Sanjay Raut on Monday said Shiv Sena leader Ravindra Waikar should be stopped from taking oath as the Lok Sabha member, amid a controversy after he won the Mumbai North West seat by a thin margin of 48 votes. The Vanrai police in Mumbai have registered a case against Waikar's brother-in-law for allegedly using a mobile phone at a counting centre in Goregaon (which is part of Waikar's constituency) on June 4, when results of the general elections were announced. Speaking to reporters here, Raut said, "Waikar's electoral victory is under suspicion, and a complaint has already been filed at the Vanrai police station in Mumbai. Due to the ongoing controversy surrounding the poll outcome, Waikar should be prevented from taking oath as a member of the Lok Sabha." "It would be a true display of democracy if he is stopped from being a Lok Sabha member until the investigation is concluded," he added.
