The party of Pakistan's famed cricketer-turned-politician Imran Khan, who has led a week of antigovernment protests in the capital, resigned from parliament on Friday in its latest bid to drive Prime Minister Nawaz Sharif from power over alleged election fraud. The move came a day after parliament presented a united front against Khan, with opposition parties backing a resolution rejecting his calls for Sharif's resignation as unconstitutional despite the presence of thousands of protesters just outside. Khan and Qadri have called for electoral reforms and the appointment of a caretaker government to hold a new vote.
