Lefts have the right to withdraw their support. But they should be very careful about the outcome of next general election. First BJP led NDA will emerge the power at centre. Congress will survive without any major lose. But the lefts will face heavy fall in Kerala and WB. Now they have 18 MPs in their fold. If forced for immediate elections they will lose more than 10 in their present numbers. They will face the same situation in WB and Tripura.
