Shiv Sena-BJP combine is the Opposition alliance in Maharashtra which has been out of power since 1999 when Congress and NCP joined hands to form the government in the state.
Congress and NCP had joined hands just months after Pawar parted ways with Congress on the issue of Sonia Gandhi's foreign origin.
