The UPA has given a "free-hand" to multi-national oil firms, which are busy in "robbing" the common man, party president Sukhbir Singh Badal alleged.
"If it is the multi-national companies which will decide on the prices, why do we need a government at the Centre?" Badal said, noting that by hiking prices a day after the general budget, government has made a mockery of budget process.
He demanded an immediate rollback of the hike, alleging that the decision was taken without taking the Parliament into confidence.
As the hike excludes local sales tax or VAT, the effective increase in prices is set to be higher.
