Petrol and diesel prices in the national capital have been raised marginally following the state government's decision to levy sales tax on the two auto fuels.

Petrol has become dearer by Rs 0.67 a litre to Rs 43.52 per litre from June 6. Diesel price has increased from Rs 30.25 a litre to Rs 30.48 per litre, oil company sources said.

"When fuel prices were raised last year, Petroleum Minister Murli Deora had asked state governments not to levy sales tax on the incremental price. Delhi government did not levy sales tax on the increased fuel price but has now decided to levy 20 per cent sales tax on petrol and 12.5 per cent on diesel," a source said.
