A spokesman for Nepal's parliament says it will vote on Sunday for a new prime minister.
Mukunda Sharma says the parliament's advisory committee met Thursday and set the date after the main political parties failed to agree on a coalition government.
A candidate must win the support of more than half of parliament's 601 members to become prime minister. But no party holds a majority.
It took 17 rounds of voting spread over seven months for Jhalnath Khanal to be elected as prime minister in February. He resigned 10 days ago, plunging the country back into a political crisis.
