Pakistan Prime Minister Nawaz Sharif appeared before a panel investigating his family’s wealth on Thursday.
This is the first time a Pakistani prime minister has been grilled by an investigative agency.
The scrutiny was ordered by the Supreme Court.
Sharif arrived at the Joint Investigation Team in Islamabad but did not speak to media. The prime minister and his children deny any wrongdoing.
The Supreme Court ruled in April there was insufficient evidence to remove Sharif from office over corruption allegations levelled by the opposition, but it ordered further investigations.
The court agreed last year to investigate the Sharif family’s offshore wealth after the opposition threatened protests after the leaking of the “Panama Papers”.
