GST, which seeks to subsume various indirect taxes like excise, sales and service tax, was proposed by the Atal Bihari Vajpayee government and subsequently supported by Congress led UPA government.
However, Ramesh said the "revolutionary change in economic policy" has not turned into a realty because of opposition by the Prime Ministerial candidate of BJP.
"He (Narendra Modi) communicates on everything under the sun, I would like him to communicate to the country why he is opposing GST, why he is opposing his own party, why he is opposing Sushil Modi...Sushma Swaraj...Nitin Gadkari... Yashwant Sinha...Let him explain," the Rural Development Minister said.
He further said there is a universal consensus on GST and all industry associations and corporates who are supporting Narendra Modi are in favour of GST.
"All industrialists who appear on TV singing the praises for Modi want GST. His party is responsible for GST, his party manifesto say GST, his party leaders want GST but this one man has single handedly derailed the entire introduction of GST," he said.
