Supporters of opposition leader Imran Khan said on Sunday that they will continue their protest in the Pakistani capital, Islamabad, after the government rejected a proposal by Khan's party for the prime minister to step down for one month. Pakistan Tehreek Insaf (PTI) said Nawaz Sharif should resign temporarily while a judicial commission investigates whether or not the 2013 general elections had been rigged. Some leaders of PTI said that the party was not willing to show flexibility in its demand for the prime minister's resignation. Khan demanded that fresh elections should be held if rigging is proved by the judicial commission. Khan's supporters are hopeful their demonstration will eventually push the government to agree to their leader's demand. Some of the supporters said they had come from abroad to join the demonstrations and vowed to carry on.
