The much awaited decision came atlast from Prakash Karat,the CPM leader.Left will withdraw support to the UPA gov.The left were very uncomfotable working with cong for the last 4 years since they are fighting directly in all the state where communits are powerful.The only binding force was the anti BJP ism.But, neverthless ,the left has accepted the cong policies for many years.Infact,they should have come out very stongly when the gov failed to check in the sky rocketing price rise of important commdities.What are the positives from the gov,left could claim.It is rural employment scheme (remain to be seen if executed properly) ,loan waiver to farmers ( will go unnoticed in a few years after fresh loans issued),stopping of some disinvestment plans(will get done from new gov with full majority) ,stopped BJP from acqiring power(prsent situation favours BJP to win the next elections).
Any how,they took the decision to break away from cong and they can safely go back to the people to garner votes that is anti cong and anti BJP and to form third force.
All these efforts will end once the next elections are over and the results will reflect the same as of today or either favour BJP.
