This is what most certainly going to happen: 1. UPA will lose the vote of confidence. 2. After next election, NDA will come to power. 3. BJP will sign the Nuclear deal with the font of the draft changing from Times New Roman to Arial 4. In the bye-elections, left will lose 13 seats from Kerala and 12 from West Bengal.
So, effectively, Deal will be signed and left will lose 25 MPs from loksabha.
