Chandigarh, May 29 -- Former Haryana finance minister Sampat Singh on Thursday accused the Centre and state governments of using fuel pricing as a tool for revenue generation and profiteering. At a briefing, Singh criticised the recent increase in petrol, diesel prices, domestic and commercial LPG cylinder prices alleging that consumers were being burdened despite a fall in international crude oil prices. Demanding an immediate rollback in fuel and gas price hikes, the Indian National Lok Dal (INLD) leader warned that the party would hold protests at district headquarters across Haryana on June 1 if prices were not reduced by May 31.

He alleged that before the five assembly elections, when crude oil prices had crossed $110 per barrel, the government had maintained there was no proposal to hike fuel prices. "However, after the elections, prices of petrol and diesel were repeatedly increased despite crude oil falling below $100 per barrel," he alleged. HTC...
