Duperval Guillaume will hold the post for a maximum of 30 days, as established by the constitution, before a permanent choice is presented to parliament by President Michel Martelly, according to Enex Jean Charles, secretary general of Haiti's council of ministers, yesterday.
The former prime minister, Laurent Lamothe, resigned a week ago amid the bitter political standoff over legislative elections.
Martelly was supposed to call elections in 2011 for a majority of Senate seats, the entire Chamber of Deputies and local offices. But several opposition senators have used parliamentary procedure to prevent a vote authorizing the election while orchestrating a series of large protests in the capital to call for the president to resign.
On January 12, the terms of the current Senate will expire and the president can sign a decree that will enable the country to hold the elections in the first half of the year.
