London/Islamabad: Pakistan's ousted prime minister Nazwaz Sharif's ailing wife Kulsoom Nawaz's health has further deteriorated following a cardiac arrest in the UK where she was undergoing treatment following throat cancer surgery.
Kulsoom, 68, was shifted to the intensive care unit (ICU) of the London hospital late last night after her condition deteriorated further, Maryam Nawaz, her daughter said.

"Ami had a sudden cardiac arrest when we were on the flight and is in ICU and on the ventilator since," Maryam tweeted.
Maryam, who flew to London along with her father, requested well-wishers to pray for her mother's health. Kulsoom was readmitted to the hospital on Wednesday, where her health deteriorated and she was immediately taken to the emergency unit in the night and has not regained consciousness since, The Express Tribune reported.
