This is the third time Sharifs stint in office has been cut short. His government was dissolved in April 1993 by President Ghulam Ishaq Khan, however Sharif successfully challenged that decision to become prime minister again in May. He then resigned from the post in July, forcing the removal of President Khan as well.After re-election in 1997, he was then forced out by a military coup in 1999. He came back from exile to secure a major victory in the 2013 polls. This latest disqualification comes roughly a year before his term was to conclude, ending his chance of creating history by becoming the first Pakistani prime minister to complete a full five-year term in office. Pakistans powerful military has ruled the country for roughly half of its nearly 70-year-history.
