Lahore, Feb 5 (IANS): PML-N President Shehbaz Sharif on Wednesday said that former Prime Minister Nawaz Sharif's treatment is being affected because his daughter Maryam Nawaz is not being permitted to be with him in London, a media report said.

In a statement, the Leader of the Opposition in the National Assembly said that it was very unfortunate that Maryam was not being granted permission to take care of her father, Dawn reported.

He said that purely on humanitarian grounds, the PML-N vice president should be permitted to be with her father.

The PML-N supremo is currently in London for medical treatment. While Maryam had sought permission to fly abroad to be with her father, the federal Cabinet in December last year decided not to remove her name from the exit control list (ECL) in the Al Azizia Steel Mills reference.

On January 14, the Cabinet placed her name on the ECL for the second time in the Chaudhry Sugar Mills case.

"As Nawaz's health is concerned, the margin for medical action is reducing as more time passes," Shehbaz said.

He said that cardiologists had to twice change the earlier decided date for his brother's cardiac catheterisation as Maryam was not with him.

Shehbaz said Nawaz's health remained "worrisome and unstable".

Further, Shehbaz said that Kulsoom Nawaz's death had a "severe negative effect" on Nawaz's health.
