Islamabad - While attention was focused on Pakistani Prime Minister Nawaz Sharif's activities in London, Finance Minister Ishaq Dar spearheaded PML-N efforts here to prepare the ground for a judicial commission to investigate the Panama Papers leaks. The Pakistan Muslim League-Nawaz on Friday persisted in its efforts to reach out to political players and contact retired judges to head the commission, Dawn online reported. Mushahidullah Khan, a PML-N senator, said he and Information Minister Pervaiz Rashid had met Mahmoud Achakzai, chief of the Pakhtunkhwa Milli Awami Party (PkMAP), for consultations on the matter. The media reported on Friday that Sarmad Jalal Osmany, a retired judge, will head a commission that would investigate the scandal. However, no one from the government confirmed the reports. A PML-N legislator said Osmany's name was on the list prepared by the government. The list consists of retired judges who could, and have been, approached to head the commission. Pakistani government's legal experts will meet Ishaq Dar on Saturday to discuss the issue. Sharif is in London on a seven-days visit for long pending medical checkups. Pakistani politicians have been keeping an eye on the prime minister's movements in the Britain after he landed in controversy following his children being named in the massive leaks dubbed as "Panama Papers".
