Former prime minister Nawaz Sharif is expected to appear before the Lahore High Court today Monday in a high treason case against him.

A three-member full bench, headed by Justice Mazhar Ali Naqvi, will hear the treason petition against former prime ministers Shahid Khaqan Abbasi and Nawaz.

Earlier, on September 24, the LHC had summoned Nawaz today as he failed to appear for the last hearing.

During the last hearing, Nawaz's lawyer Advocate Naseer Bhutta apprised the court that Nawaz was unable to appear before it as people were frequently visiting him to condole the passing of his wife Begum Kulsoom. He further requested the court to fix the hearing for a date after his wife's chaliswan (forty days of mourning).

Accepting to the postponement request, Justice Naqvi fixed the hearing for today.

The petition, lodged by Advocate Azhar Siddiqui, alleges that Abbasi shared crucial details of the National Security Council (NSC) meeting with Nawaz following his statements on the 26/11 Mumbai attacks.

By leaking details of the NSC Abbasi committed high treason, the petition says.

The petitioner had argued that Nawaz's controversial interview to a newspaper had dented the country’s image and sovereignty. He further alleged that Abbasi supported Nawaz in the matter.
