If a virtual washout of the winter session was not reason enough for Modi Sarkar to worry, Trinamool Congress threatening to reconsider Goods and Services Tax or GST has now got a backing from the most unlikely quarter: it's arch enemy CPIM.

Earlier giving a jolt West Bengal finance minister Amit Mites said, "My concern is the double whammy of the common poor people. It has hit the common man hard. It has been a massive destabilisation resulting in transactional cost (loss) of Rs 1.28 lakh crore in 50 days. It is a complete de-empowerment of the small and medium and even large enterprises," And hence the TMC wants to do a rethink.

But this statement has now got the backing of CPIM politburo member Brinda Karat too. Speaking to India Today, Karat said, "Look things are no longer the same as it was before demonitization. Every state economy had taken a hit. For instance Kerala has taken a hit of 25 to 30 pc. And in such a scenario every state will have to figure out what is in its interest".

Something that has the potential to jeopardise the GST particularly when the economy needs this new reform to overcome the downturn post the cash crunch. To make things worse, BJPs own Rajya Sabha MP Subramanian Swamy has taken pot shots at its own government. In his tweet, Swamy said that he agrees with Mitra that the GST rollout must be postponed following the "hit" the economy is already taking with the currency ban. Something that will be music to Mamata Banerjee's ears. But nothing less than a shock for the BJP.

WB Finance Minister is right. First digest demonetisation then after restructuring GSTN we can consider GST &; Subramanian Swamy (@Swamy39) December 1, 2016

With country staring at a economic slowdown, this surgical strike by TMC, left and Swamy alike on the treasury benches has left economists predicting a gloomy economy ahead.
