Islamabad, May 03 (ANI): Pakistan's cricketer-turned-politician Imran Khan announced that he and his party would boycott Geo and Jang Media Group over what he said was the media group's "role in rigging" during the national elections held last May. Khan said neither he nor any member of his party would appear on Geo TV until they receive an apology. He said Geo was responsible for airing a victory speech of Nawaz Sharif at a time when the election results had not been fully counted. Khan , who is Chief of Pakistan Tehreek-e-Insaf (PTI), said his party had issued a white paper in which it has revealed instances of rigging that had come to light after the party's investigations.
