After raising petrol price by a record Rs 21.58 per litre and diesel by Rs 19.18 since the government raised excise duty to an all-time high in March last year, state-owned fuel retailers, IOC, BPCL and HPCL had reduced petrol price by 67 paise a litre and diesel by 74 paise per litre effected between March 24 and April 15. Oil companies, which have in recent months resorted to an unexplained freeze in rate revision, had hit a pause button after cutting prices marginally on April 15. This coincided with electioneering hitting a peak to elect new governments in five states, including West Bengal.
