The party, led by state Finance Minister K M Mani, said the government should intervene in reducing the price of petroleum products in proportion with the reduction of crude oil price in the international market.
In a recent letter to Prime Minister Narendra Modi, KC-M General Secretary and former MLA Joseph M Puthusserry said the Centre should withhold the right to control the petroleum products in itself for the sake of common people.
He said the petroleum companies follow the practice of re-examining the petroleum price between 1st and 15th of every month in accordance with the change in the international market.
"But the sad but an interesting fact is that only the hike in prices is taken into concern, the decrease of crude oil price in the international market is not at all taken into account by these companies," he said.
The senior leader also alleged that the union government had increased the excise duty on petroleum products four times between November 12, 2014, and January 17, 2015 and by doing so it had swept away the benefits of the common public instead of decreasing the price of crude oil.
