LONDON: Hussain Nawaz, the son of former prime minister Nawaz Sharif, said late Wednesday his mother was feeling better but was still undergoing medical treatment, Geo News reported.

Kulsoom Nawaz, who recently underwent a throat surgery and, at present, is residing at her son Hasan Nawaz's residence, is in London for the treatment of lymphoma since late last year. 

Speaking to media personnel, Hussain said the doctors overseeing his mother's treatment have asked her husband, Nawaz Sharif, to fly out to London to make further decisions since her health was an important matter.

Consequently, the former premier decided to file an appeal to the court to grant him a leave of absence.

Kulsoom Nawaz "remained in the hospital for 10 hours and had to be brought again the next day", Hussain added, noting that she was "given drips".

"She wished to return home, so we brought her back with us. The doctors, however, have requested her to stay under their care.
