MUMBAI, June 20 -- Rebel Shiv Sena (UBT) MP Omraje Nimbalkar on Friday said he was exiting the party to join the Eknath Shinde-led Shiv Sena, and said the decision was "not driven by greed for money." He said the move was crucial to keep up the fight against rivals in the extended family, allegedly responsible for the killing of his father Pawanraje Nimbalkar. The main accused in the case is his uncle and former NCP minister Padamasinh Patil whose son Rana Jagjitsinh is a BJP MLA. "The governing coalition obstructed my efforts...I was compelled to take this decision to counter the might of the rivals who are strongly backed by BJP," Nimbalkar told HT. A Congress leader at the time, Pawanraje was shot dead in Navi Mumbai on June 3, 2006....
