BJP chief Amit Shah yesterday tore into the Congress over its "failure" to tackle unemployment and other problems and its criticism of the GST, saying it was not a 'Gabbar Singh Tax' but the revenues go to pay for 'one rank, one pension' and subsidises the poor. In his maiden address in the Rajya Sabha, he asked whether the Congress was inciting the people not to pay taxes, as he listed out the NDA government's achievements. Shah took on senior Congress leader P Chidambaram for his 'pakoda' jibe.
