Modi had launched the tax at a special midnight session of Parliament, arguing that it would help the poor of the country. It was clear that he hoped to take political credit for the move. The Congress, Dravida Munnetra Kazhagam, Trinamool Congress and the Left had boycotted the event. Since then, given the distress the tax regime has caused, Modi has been on the back foot and has sought to temper his ownership of the decision to introduce it. While campaigning in Gujarat in October 2017 ahead of Assembly elections, Modi called the Congress “an equal partner in Goods and Services Tax decisions”.

By contrast, Congress president Rahul Gandhi has repeatedly called the tax a “Gabbar Singh Tax”, referring to the famous Bollywood dacoit. With Modi announcing that rates might be cut, the Congress was quick to take credit for the idea with party leader Randeep Singh Surjewala tweeting:

In May, Malaysia’s voters delivered a shock verdict, unseating the Barisan Nasional coalition after six decades in power. A major factor behind the verdict was the introduction of a Goods and Services Tax three years ago. To make the comparison even more uncomfortable for the BJP, Malaysia’s Goods and Services Tax was simpler and less burdensome than India’s – it had one 6% slab for all goods and services. The state election verdicts, and probably the Malaysia poll results as well, will be at the back of Modi’s mind as he decides his Goods and Services Tax strategy for the Lok Sabha elections in 2019.
