The MVA government in Maharashtra plunged into a political crisis on Tuesday with a major revolt in Shiv Sena led by urban development minister Eknath Shinde, a powerful grassroots leader who has long felt sidelined. This is seen as one of the biggest rebellions in the history of the 56-year-old party and the first that CM Uddhav Thackeray is facing after the death of his father Bal Thackeray.
