Pakistan Prime Minister Nawaz Sharif is set to become the first sitting prime minister to appear before any investigating agency. He will appear before the joint investigation team (JIT) constituted to probe money-laundering allegations against his family on Thursday. <br/><br/>The summons was issued by the JIT last week asking Mr. Sharif to appear before the six-member probe team this Thursday. The JIT's summons also reminded the Prime Minister to bring along relevant record, documents, material related to the Panama Papers case. <br/><br/>This will entail nearly all the documents and evidence submitted before the Supreme Court by Mr. Sharif's counsel. Sources said that Finance Minister Ishaq Dar may also be questioned by the team before the PM's appearance.<br/><br/>The Joint Investigation Team, formed by Pakistan Supreme Court to probe the money trail of the property owned by Sharif family in London, had questioned Sharif's sons – Hussain and Hasan – last month over the family's alleged improper business dealings.
