New Delhi, March 26 (TIWN) State-owned oil marketing companies (OMC) on Saturday raised petrol and diesel prices for the fourth time this week.

These increase increases are the steepest single-day rise since the daily price revision was started in June 2017.

In four increases, petrol and diesel prices have gone up by Rs 3.20 a litre.

Prices had been on a freeze since November 4 ahead of the assembly elections in states like Uttar Pradesh and Punjab -- a period during which the cost of raw material (crude oil) soared by about $30 per barrel.

The rate revision was expected soon after assembly elections ended on March 10 but it was put off.
