This handout photograph released by the Shaukat Khanum Memorial Hospital (SKMH) shows Pakistani politician Imran Khan, the head of Pakistan Tehreek-e-Insaaf (PTI) party, leaving the hospital in Lahore on May 22, 2013 . Khan left hospital on May 22, two weeks after breaking bones in his back in a fall at a rally for the country's general election, where his party scored a major breakthrough. The 60-year-old was ordered to remain immobile in bed after he fractured vertebrae and a rib in a dramatic tumble from a hoist lifting him to a stage just days before the May 11 general election.
