The central government should roll back the fuel price hike, Lok Janshakti Party (LJP) chief Ram Vilas Paswan said in Patna on Saturday during a statewide shutdown in Bihar.
The price hike should be withdrawn in "people's interest", he said.
The central government ended curbs on petroleum pricing and hiked the prices of diesel, kerosene and cooking gas last month.
The LJP and Rashtriya Janata Dal (RJD) enforced the statewide shutdown to protest the fuel price hike and rising prices.
Paswan said he and RJD chief Lalu Prasad will raise the fuel price hike issue in the monsoon session of parliament beginning July 26.
The LJP chief was elected to the Rajya Sabha last month.
Paswan also said his party and RJD would not join hands with the Bharatiya Janata Party-led NDA. "We cannot go along with NDA on this or other issues," he said.
