Former prime minister Nawaz Sharif landed in Lahore on Sunday after spending over 10 days in London, DawnNews reported.

The former premier arrived in the city with his daughter, Maryam Nawaz, and headed straight to his Jati Umra residence. On Dec 5, the two had departed for London to see Kulsoom Nawaz, the former prime minister's wife, who has been undergoing treatment for cancer in the British capital for some time.

Addressing media in London before his departure for Pakistan on Saturday, Nawaz had announced that he would spearhead a fully-fledged movement for the rule of law and supremacy of the Constitution in the country.

The announcement had come after the Supreme Court rejected PML-N leader Hanif Abbasi's petition for Pakistan Tehreek-i-Insaf (PTI) Chairman Imran Khan's disqualification.

On Saturday, Nawaz had bitterly criticised the apex court, alleging that it had adopted double standards in handling his case and that of the PTI chief.

Drawing parallels, Sharif said that while he had been sacked in the Panama Papers case for not receiving a salary — amounting to a few thousand dirhams — from his son’s company, Imran Khan had been acquitted despite the fact that he had admitted to having hundreds of thousands of pounds worth of business transactions through his offshore company Niazi Services Ltd.

“This double standard is not acceptable anymore and I’ll launch a movement across the country with full force for the supremacy of law and Constitution,” he had declared.

Nawaz and his daughter are set to appear before an accountability court in Islamabad in corruption cases next week.
