"It is a matter of concern that Oil Marketing Companies (OMCs) have increased the price of diesel which will spur inflation," she said in a statement here tonight.
It was especially a matter of concern that the hike of 50 paise came at a time when inflation, particularly food inflation, had not dropped to expected levels.
"Today's hike is based on wrong policy of the previous Congress-led coalition government," she said, apparently referring to the monthly revision of diesel prices.
Poor people are worried because of this, she said, adding, such a price hike will have a 'chain reaction' as diesel price hike could result in increase of other goods, including essential commodities such as fruits and vegetables.
Stating that Modi was ushering in changes in many fields, she said he should also focus on changing the petroleum pricing policy as suggested by her many times.
