" Left" is very good at doing a double act, They support DMK and Congress in Tamilnadu while they are dead against Congress in Kerela. They mean no harm to Dr.Singh nor UPA Govt, They will call for nation wide strike against 123 (Their Nation means Kerela and WB) and talk about withdrawing the support, we know that left itself is on life support system how can they with draw support for UPA ?.
