Maharashtra's border dispute with Karnataka needs to be approached aggressively, and all parties must unite to bring back the Marathi-speaking region into the state, Chief Minister Uddhav Thackeray today said at a meeting with the top leaders of the ruling alliance. "CM Thackeray said this matter needs to be taken up aggressively. To bring back the Marathi speaking region of Karnataka into Maharashtra, all parties in the state need to come together and appeal to the centre," a tweet by the Chief Minister's Office (CMO) in Marathi said.
