Islamabad: Pakistan Prime Minister Nawaz Sharif’s elder son Hussain Nawaz on Tuesday appeared for the sixth time before a Joint Investigation Team (JIT) probing the high-profile Panamagate graft case against his family.

Hussain Nawaz arrived at the Federal Judicial Academy and was questioned by the JIT set up by the Supreme Court.

As the JIT deadline of July 10 approaches, two members of the six-member JIT on Tuesday left for Qatar to record the statement of Shaikh Hamad Bin Jassim Bin Jaber Al Thani.

Irfan Naeem Mangi from the National Accountability Bureau and Brigadier Kamran Khurshid from Military Intelligence departed for Doha early Tuesday morning on Qatar Airways flight, the Dawn reported.

Shaikh Hamad had written two letters to the Supreme Court in which he said that late Mohammad Sharif, father of Nawaz Sharif, had invested Dh12 million in the real estate business of the Qatari royal family.

In its judgement of April 20 in the Panama Papers case, the Supreme Court had constituted a JIT and empowered it to summon the prime minister, his sons and any other person necessary, to investigate allegations of money-laundering, through which the four apartments in London’s posh Park Lane area were purchased.

According to letters by Shaikh Hamad, the money invested by late Mohammad Sharif was returned to the family with profits.

Sharifs have maintained that the same money was used to buy London property.

On May 5, the Supreme Court set up a high-level six- member JIT to probe Sharif and his sons’ alleged corruption in the Panama Papers case.

It has already questioned Sharif and several others of his family, including his sons — Hussain and Hasan — over the family’s alleged improper business dealings.

Sharif’s daughter Maryam Nawaz will appear on Wednesday before the JIT for the first time.

Sharif has denied any wrongdoing and said the property was purchased through the money his late father had invested in the Gulf states.

However, opposition parties allege that the property was bought through illegal money which Sharif got in 1990s when he served twice as prime minister.

The JIT is expected to complete its probe by July 10 and submit a report to the Supreme Court, which will decide fate of Sharif. The JIT comprises anti-corruption officials, along with members of the powerful spy agency ISI and the Military Intelligence.

Chairman Pakistan Tehreek-e-Insaf (PTI) Imran Khan said that Panama Leaks case is changing the history of Pakistan as big dacoits are being held accountable.

Talking to the media here on Tuesday, he said that influential persons were being probed for the first time for their alleged corruption. He said that children of Prime Minister Nawaz Sharif and Finance Minister Senator Ishaq Dar have become billionaires due to alleged corrupt practices. He said if this amount is spent on welfare of the youth, it will help end unemployment in the country.

“The major problem of the country is the scarcity of pure drinking water. Most of the children in the country die due to this problem. Provincial capital Lahore where 57 per cent of the annual budget is spent on development works, some 60 to 70 per cent of citizens have no facility of pure drinking water. It is the responsibility of the state to provide pure drinking water to its citizens”, he added.
