Our PM Mr. Manmohan Singh knew it very well that Left Parties are nothing but barking dogs and seldom do they bite. That's the reason PM has challenged them on their face. Now you see that Left Parties would go underground and latter they would come out with a statment that they have decided to support the UPA due to the fact that they need to prevent communal forces from coming to power. Left Parties have been Bullshitting every sensible citizen of this country. They can't dare to take independent steps. GOD must save these guys from ruining this country.
