Maharashtra Chief Minister Eknath Shinde on Thursday said he has taken a "contract" for development of the state and to ensure prosperity and welfare of its people, hitting back at his opponents over their constant jibe at him since assuming the top office.

Speaking in the Assembly, Shinde defended his revolt against the Shiv Sena leadership in June, which brought down the two-and-a-half-year-old Maha Vikas Aghadi (MVA) government, and asserted his act was neither unconstitutional nor illegal.
