Sharif's close aide and minister for development Iqbal later said, "If you review this report, it has no logical argument neither it quoted authentic sources nor material, but is based on things that have no authenticity before the law".
With the Supreme Court now taking up the case once more, Sharif's political career hangs in the balance.
In the April 20 verdict, the Supreme Court gave JIT two months to find out answers to 13 questions related to the money trail of Sharif properties in London.
PML-N leader barrister Zafarullah Khan said that the report submitted to the apex court today was not a report by the JIT but of the PTI.
However, according to the Dawn, the JIT's report stated that the "financial structure and health of companies in Pakistan" linked to the Sharif family "do not substantiate" their wealth.
Noting that the Sharif family's lifestyle does not match their income, it said the ruling family may be deemed guilty of violating the NABs' reference.
The premier reaffirmed that neither he nor his family ever participated in corrupt practices, adding that all documents required by the JIT were handed over.
The investigators have recommended that a case be filed against Sharif in the a National Accountability Court, after concluding that there were "significant gap [s]" in Sharif's family's ability to account for their assets.
The officials said, the report of the investigators was handed over to the Supreme Court on Monday. The court slapped a contempt notice on the printer publisher and reporter of largest media group Jang for misreporting on the facts of the JIT probe and contacting a judge on his report.
The Prime Minister has been denying any wrongdoing since his name appeared in Panama Papers a year ago.
It also highlighted "irregular movement" of huge sums of money in the form "loans and gifts" between Sharif and his youngest son from various companies set up in Saudi Arabia, the United Kingdom and the UAE.
Sharif himself appeared before the inquiry on June 15, while his sons Hassan and Hussain were questioned multiple times during the course of proceedings.
However, PML-N leaders continue to claim innocence about the involvement of Sharif and his family members.
