An empowered Group of Ministers will meet in New Delhi on Friday to consider freeing of petrol prices from government control. If aligned with the international rates, petrol price in the country will go up by 3.73 Rupees a litre. According to official sources, domestic retail prices are benchmarked at close to 60 US dollars per barrel crude oil price while the global rates currently are over 77 US dollars a barrel. Petroleum Minister Murli Deora has already asked states to lower sales tax on petrol and diesel to cushion consumers from the impact of fuel price hike.
