Islamabad, Dec 4 (IANS): Pakistan has written to the British government seeking the return of ailing former prime minister Nawaz Sharif after his medical treatment in the UK is over.

This was disclosed at the ARY News talk show 'Power Play' on Tuesday.

Sharif is facing scores of charges in several cases in Pakistan, and is also convicted in a case, said the government letter to the authorities in the UK.

The letter has annexed details of the cases against Nawaz Sharif.

Sharif had left for London in an air ambulance via Doha, accompanied by his younger brother, Shehbaz Sharif and personal physician and reached London on November 19.

Earlier, the Lahore High Court had allowed the former premier to go abroad for four weeks without submitting any indemnity bond as proposed by the federal government.

A two-member bench headed by Justice Ali Baqir Najafi ordered the federal government to remove the Pakistan Muslim League-Nawaz (PML-N) chief's name from the Exit Control List (ECL) without placing any conditions.

The bench, which was hearing the plea filed by PML-N seeking unconditional removal of Nawaz Sharif's name from ECL, also maintained that the duration of his visit could be extended if his health required.
