Beleaguered Pakistan President Asif Ali Zardari has been admitted to a Dubai hospital following heart complications, triggering intense speculation that he may step down in the face of army pressure over the 'memogate' scandal.
Shehbaz, the 70-year-old younger brother of former three-time prime minister Nawaz Sharif, has served as chief minister of the country's most populous and politically crucial Punjab province thrice.
Hours after Pakistan President Asif Ali Zaradri suddenly returned home in the thick of brewing standoff over the memogate affair, the army sought to dispel impression that a telephonic conversation between him and its powerful chief Gen Ashfaq Parvez Kayani had anything to do with the "some events" in last 72 hours.
The charged PTI supporters, including women and children, showed their solidarity with Khan during the rally that started at 9 pm on Sunday and lasted till 3 am on Monday.
The move came hours after Khan was removed from office through a no-confidence vote held early Sunday morning, becoming the first premier in the country's history to be sent home after losing the trust of the House.
