Mysuru: Karnataka Chief Minister Siddaramaiah, on Monday, hit out at the Union government and said that Prime Minister Narendra Modi was the one who introduced the Goods and Services Tax (GST) and later raised the rates and now he is taking the credit for the next-generation GST reforms in the country. It was PM Modi who introduced GST, it was PM Modi who kept raising GST rates, and now it is PM Modi again patting himself on the back," Siddaramaiah said in a veiled attack at the Prime Minister. "Now they (BJP) want to hold a "GST Savings Festival", but weren't they celebrating a "GST Loot Festival" for the last eight years?" "When Rahul Gandhi repeatedly demanded in the past that the "Gabbar Singh Tax" be reduced, BJP mocked him. Today, shaken by public outrage, they have reduced GST -- yet shamelessly try to take credit for it," he added.
