Nepal's major political parties agreed on Monday to form an interim government under supreme court Chief Justice Khilaraj Regmi and hold elections in June.
Nepal hasn't had a working parliament since May and Maoist Prime Minister Baburam Bhattarai has been running a caretaker government.
But it has been unable to hold elections, with opposition parties demanding Mr Bhattarai go before a vote is held.
The PM's office confirmed that his party is ready to support Mr Regmi's selection.
Mr Regmi is expected to be appointed to a three-month term as prime minister, after which he would return to court.
A new deal would have to be made if elections aren't held in that time.
