Party leader Ashutosh said the names of several actors, politicians, kin of an industrialist, "close" to the ruling party, have cropped up in the papers, but the Centre has failed to take any action against them.
He claimed that instead of launching an investigation into the Panamagate scandal, the Centre is "hounding" leaders of opposition parties using agencies under it.
"But Modiji and the Centre are covering up corruption by own partymen," he alleged.
Sharif was today disqualified from office by the country's Supreme Court, which also sent his case to an anti- corruption court for trial in the Panamagate graft scandal.
Panama papers are leaked documents of about 1.15 crore files containing details of about 2.15 lakh bank accounts. The documents were leaked from law firm Mossack Fonseca headquartered at Panama.
