The Prime Minister's daughter, Maryam Nawaz, seems to have falsified documents in an effort to hide her possession of some overseas properties.
"The JIT [Joint Investigative Team] report about our family businesses is the sum of hypotheses, accusations and slander", Sharif said according to Reuters. The children of Pakistani Prime Minister Nawaz Sharif were among those customers, and they showed holdings that the Sharif family had failed to publicly declare. And while owning property in itself is not illegal, opposition parties have questioned if the money to buy them came from public funds.
Sources close to PML-N said it was an important meeting to woo some of the disgruntled backbenchers of the party whose support would be key for the prime minister.
One of the most shocking discoveries was that the text in documents Maryam sent to the investigators, allegedly from 2006, was rendered in the "Calibri" font, which only became available on January 31, 2007, the report published by Express Tribune, says on page 54.
Experts told the BBC that a beta version of Windows 2007 had been available since 2004, but the inventor of the Calibri font, Lucas de Groot, told the BBC, "that beta versions were generally only used by "tech geeks" rather than normal companies or government officials".
In their report, which has been leaked to media, the team alleged Sharif's family accumulated wealth far above its earnings, and says his children, including heir-apparent Maryam Sharif, signed falsified documents created to mask the truth.
The Supreme Court is likely to take up the JIT report on Monday.
"If the person using Calibri was such a font lover that he or she HAD to use the new Calibri, then he or she should be able to prove that other documents were printed with Calibri in 2006, and these prints should be in the hands of other people as well".
The Pakistan Prime Minister has been under pressure since documents leaked in 2016 from a Panama-based law firm which disclosed that his family had offshore accounts.
It said the ruling PML-N party may urge Sharif to stay on in office and Sharif may be tempted to do so, "but the toll on democracy would be too great". In the meantime, the country's apex court will decide on how to proceed with the JIT's report and whether to call for a trial.
Sharif's government has slammed the report, with Planning Minister Ahsan Iqbal branding it "a piece of trash".
"Pakistanis on Twitter were quick to mock the Sharif family's lapse of judgment, and the hashtag #CalibriGate soon went viral, with tweets like, "Always do corruption in Arial", "#Calibri is our very own Covfefe", and "Cause of Death: "Calibri".
