PORT-AU-PRINCE (AP) — Haiti’s Prime Minister Garry Conille abruptly resigned his post, giving the country a new political crisis that is likely to distract the government and further delay efforts to rebuild from the devastating January 2010 earthquake.

The prime minister’s resignation on Friday had been rumored for weeks but it still sent shockwaves through a country accustomed to political turmoil. President Michel Martelly addressed the nation in a televised speech, thanking Conille for his service but giving no word on whether he had chosen a successor.

“Of course, I regret that the resignation occurs in a context in which the country is beginning to take off,” said Martelly, whose first two picks for prime minister failed to win approval in parliament last year, largely paralyzing the government for the first five months of his term.

Conille’s departure means Haiti will not have anyone to run the day-to-day operations of the government, a situation that will likely last at least for weeks before Martelly and the opposition-dominated Parliament can agree on a replacement.

It is a situation that observers fear will prompt international donors to withhold aid pledges and prevent action on the contracts necessary for reconstruction from the quake that left much of the capital in ruins.

“Haiti doesn’t have any give, there’s no cushion,” said Mark Schneider, a senior vice president and Haiti expert with the nonprofit think tank International Crisis Group in Washington, D.C. “Anything that in another country is just a setback becomes a major setback because the challenges are so great.”

The earthquake yielded an outpouring of sympathy and support. Donors pledged $4.5 billion in aid but only about half that amount has been released and Haiti has hobbled from one crisis to the next, which has made rebuilding a piecemeal effort.

One of the donors, the World Bank-run Haiti Reconstruction Fund, has more than $100 million on hold pending the government’s approval of projects to be carried out in a transparent and coordinated manner.

Josef Leitmann, administrator for the Haiti Reconstruction Fund, said that the “instability doesn’t instill confidence” among donors but that the agency would “work with the government that’s still in place — that’s the presidency and the parliament.”

Others were more concerned. Senate president Simon Dieuseul Desras warned that the loss of the prime minister would create a political vacuum.

“This is not what the population was waiting for, that the Parliament and president’s office are in conflict,” Desras told The Associated Press. “Today is a waste of time. We must start all over again and we don’t know how long it will take to have another prime minister again.”

At least two candidates were being considered as a replacement, including Foreign Affairs Minister Laurent Lamothe and Ann-Valerie Milfort, the interim head of the now-defunct Interim Haiti Recovery Commission, according to a government official who spoke on condition of anonymity because he was not authorized to release the information.

Martelly said in his public speech he had been in contact with Desras and the head of the lower Chamber of Deputies, and that his office and lawmakers are working to strengthen their relationship.
