Virginia (U.S): July 11 (ANI): In a tete-a-tete with ANI, Union Transport Minister Nitin Gadkari expressed hope of passing of the Goods and Services Tax (GST) bill in the current Parliament session. He said lots of state governments, including non-BJP ruled, are in favour of the GST as it would increase tax revenue in the state. Speaking on the questions being raised by the Congress on GDP figures taken out by the present Government, Union Transport Minister Gadkari said the approach of Congress party is not constructive. He alleged that the Opposition didn’t want to appreciate BJP and Prime Minister Modi's success in the mission. He further added that the allegations made by Congress were baseless since statistics and data is available to refute their assertions.
