ISLAMABAD: Pakistan Tehreek-i-Insaf (PTI) spokesman, Naeemul Haq, on Sunday alleged Prime Minister Nawaz Sharif lied about his recent open-heart surgery.

In an interview with DawnNews, Naeemul Haq said, "Nawaz Sharif lied about his illness and released a false statement from there [London]. There was no doctor's name and no open-heart surgery."

"We have received lots of information from doctors in London," he claimed.

When asked whether this was the PTI's official stance, Naeemul Haq said, "This is the case according to my knowledge."

The PTI spokesman was of the opinion that the premier "wants to hide wrongdoings that were exposed by the Panama leaks" and that "Nawaz Sharif is the only danger to democracy."

"For three months, he has fooled the people on the Panama issue," he added.

The PTI spokesman said the party along with other opposition parties had, after a number of discussions, agreed on two points: that the Panama leaks should be investigated and that corruption must end.

A PM House spokesperson said they were not aware of Naeemul Haq's allegations and did not offer a comment on the matter.

Nawaz Sharif underwent open-heart surgery at a London hospital on May 31. The need for the surgery arose after the premier went through a cardiac procedure called Atrial Fibrillation Ablation in 2011, during which certain complications occurred resulting in perforation of heart, Maryam Nawaz earlier told the media.

Many had called it a politically imprudent decision to leave the country at a time when opposition parties were exerting pressure on the government in the wake of the Panama leaks. However, a PML-N officer-bearer had told Dawn that Nawaz's medical condition necessitated the visit.
