ISLAMABAD:- Pakistaninfo-icon Prime Minister Imran Khaninfo-icon has said the incarcerated former premier Nawaz Sharifinfo-icon tried to secure his release with the help of two friendly countries.

Addressing mediainfo-icon persons in Islamabad on Monday, Khan did not reveal the names of the two nations but said that they just conveyed to him the message but did not press for Sharif's release.

"They told me that we will not interfere," said Khan, who was accompanied by the adviser on finance, Hafeez Sheikh, and Federal Board of Revenue Chairman Shabbar Zaidi.

Sharif, 69, has been serving a seven-year prison term at the Kot Lakhpat Jail in Lahore since December 24, 2018 when an accountability courtinfo-icon convicted him in one of the three corruptioninfo-icon cases filed in the wake of the Supreme Court's July 28, 2017, order in a Panama Papers case.

Sharif and his family have denied any wrongdoing and allege that the corruption cases against them were politically motivated.

In May, the Supreme Court rejected his review petition seeking bail on medical grounds and permission to go abroad for medical treatment.

Khan said that those convicted for corruption would not be allowed to go away until they gave back the stolen money.

Former president Asif Ali Zardari is in the custody of the National Accountability Bureau (NAB) for his role in corruption cases.

"A plea bargain can be allowed and no foreign country can do anything in this regard. They [Sharif and Zardari] will have to pay the money," Khan said.

Zardari has been named in a multi-million dollar money laundering case along with his sister Faryal Talpur.

During the occasion, Khan also spoke about the economyinfo-icon and said that it would improve as the difficult time was over. Khan said his government had spent $10 billion on debt servicing on loans taken by previous governments. "A comprehensive plan is being devised including new legislation to control smuggling and money laundering," he said.
