Taking a dig at the BJP's claim that the Centre was looking at ways to arrest the hike in fuel prices, Congress leader P Chidambaram Sunday said the ruling party might have found a way to get "free" crude oil.
In a series of tweets, the former finance minister also attacked the Narendra Modi government for allegedly failing to curb the flow of black money in the economy.
While the Union government has asserted that it will not cut fuel prices, the Bharatiya Janata Party president Amit Shah has claimed that the "Centre will soon arrest fuel prices", said Chidambaram in a tweet.
"BJP must have found a crude oil source that will supply crude oil free!," he quipped.
Shah had on Saturday blamed international developments for the rising petrol and diesel prices and dipping rupee value.
