Congress-leader Sanjay Nirupam has warned his party and NCP against allying with the Shiv-Sena to form the government in Maharashtra. Nirupam, who called it a "disastrous move", was responding to party-colleague Milind Deora, who took to Twitter on Sunday to suggest Maharashtra-Governor Bhagat-Singh-Koshyari extend an invitation to the Congress-NCP-alliance to form the government given BJP and Sena have been unable to agree a power-sharing-deal.
