Nepal's president has ordered parliament to hold a vote for a new prime minister after the main political parties failed to agree on a coalition government. President Rambaran Yadav sent a letter to parliament on Wednesday ordering it to begin the election process. He had set an Aug. 21 deadline for the parties to reach an agreement on a coalition government with representatives from each group. He then extended it for three more days, but the parties were unable to reach a consensus. Former Prime Minister Jhalnath Khanal resigned 10 days ago, plunging the country back into a political crisis.
