Both LPG and fuel prices have been hiked several times since the the Assembly election results of Uttarakhand, Uttar Pradesh, Manipur, Goa and Punjab were declared on March 10.

Fuel prices were last hiked on April 6, when the rates of petrol and diesel were increased by 80 paise each. The prices of petrol and diesel have increased by Rs 10 in total after the Assembly election results.

Meanwhile, the price rise indicator in wholesale markets was at 15.08% in April. It has now remained in double digits for 13 consecutive months.
