The Uddhav Thackeray faction of Shiv Sena, reduced to a minority in the Maharashtra assembly, has appointed a new Chief Whip for the Lok Sabha, fearing revolt by party MPs. Senior party leader Sanjay Raut wrote a letter to the Lok Sabha Speaker today and informed him that Rajan Vichare has been appointed the Chief Whip, replacing Bhawna Gawli.
