Former prime minister Nawaz Sharif on Saturday criticised the Supreme Court's (SC) decision in Imran Khan's disqualification case, and announced that he will "launch a movement for the provision justice in the country", DawnNews reported.

"Dual standards of justice would not be tolerated in the country," Sharif said while talking to media in London before leaving for Pakistan.

Commenting on the SC's decision, which rejected Hanif Abbasi's petition for Khan's disqualification, Sharif said all his predictions were coming true.

"It is dual standard of justice; my virtual salary — which I never withdrew — was considered an asset, whereas their [Imran Khan] businesses worth tens of thousands of pounds and offshore company Niazi Services were not considered an asset, despite they owned them," he said.

He alleged that the SC bench was issuing clarifications regarding the businesses and the company of Khan.

Further criticising the role of the apex court, Sharif complained that Khan filed a four-page case against him and sat calmly in his house, whereas, the bench acted as a party against him.

"And when we filed a case against Imran Khan, the bench acted as a counsel [representing Khan]," he said, adding that the difference [in the handling of both the cases] was evident.

Sharif further said, "Such type of justice will not be tolerated and we will launch a forceful movement against it. The time has come to bring the ideology of necessity to an end."

He said: "My struggle is for the supremacy of law and the Constitution in Pakistan, and I am willing to pay every price for this."
