Oil minister Dharmendra Pradhan on Thursday voiced optimism that petroleum products will be brought under the GST purview, which will help in checking volatility in fuel prices.

"In the long run, petroleum products are bound to be included within the ambit of the GST regime It is only a matter of time.

It will immensely help in containing prices of petrol and diesel," Mr Pradhan told reporters in Bhubaneswar, according to news agency Press Trust of India.6.

He, however, declined to specify any timeline on bringing petroleum products under GST.

Petrol prices are currently regulated by states which levy their respective sales taxes or value added tax on these fuels.State capitalPetrol price on June 8 in Rs. per litreDiesel price on June 8 in Rs. per litreAgartala73.1166.66Aizwal73.2465.85Ambala77.5369.09Bangalore78.6869.76Bhopal83.0372.18Bhubhaneswar76.2373.52Chandigarh74.4666.6Dehradun78.5468.91Gandhinagar76.7273.71Gangtok80.4570.3Guwahati79.671.6Hyderabad82.0174.54Imphal75.4966.64Itanagar73.2665.83Jaipur80.1873.03Jammu79.1269.74Jullunder82.6668.48Kohima75.8666.92Lucknow78.0268.74Panjim71.3569.8Patna82.8973.27Pondicherry76.1970.84Port Blair66.7164.27Raipur77.8174.04Ranchi77.1872.4Shillong76.7868.38Shimla77.5868.21Srinagar81.8171.96Trivandrum80.5573.4Silvasa75.369.4Daman75.2369.33(Source: iocl.com)7.
