The United Nations and its partners in Haiti expressed their "deep regret" that, for the fourth time in as many weeks the country's National Assembly was unable to deliberate on interim governance arrangements.

In a joint statement on Saturday, the Special Representative of the Secretary-General in Haiti and Head of the UN Stabilization Mission in Haiti (MINUSTAH), Sandra, and other members of the international community in Haiti represented in the "Core Group "(the ambassadors of Brazil, Canada, France, Spain, the United States and the European Union, and the Special Representative of the Organization of American States) cited" the lack of a number parliamentary leading to lack of quorum "as the reason for the discussions that have failed.

"Haiti continues to face serious long-term socio-economic challenges and humanitarian. These challenges can not be fully addressed in an environment of institutional instability", the CORE Group said, reiterating calls on parliamentarians to resume the session of the national Assembly and to "take action to end the uncertainty that prevails."

"Reiterating the need to return to constitutional order, the" Core Group urges all actors to ensure the completion of the electoral process, "the statement added.

On February 14, the Haitian National Assembly elected Jocelerme Privert as interim president of the island nation, a week after former President Michel Martelly left no successor.

Privert was interim president for 120 days, and an election was scheduled for April 24, following an agreement - known as the Agreement of February 5 between Haitian stakeholders to preserve institutional continuity and facilitate the electoral process.

Subsequently, on April 25, the spokesperson of the Secretary General of the UN Ban Ki-moon issued a statement stressing the concern of the UN chief that the agreed date for the holding of elections in Haiti  has not been reached and no alternative election schedule was announced.

In June, when the 120 days mandate of interim president Privert had ended, the CORE Group had asked the National Assembly to take steps to achieve a solution that avoids an "institutional vacuum", and to facilitate the return to constitutional order through elections.

On Friday, the Secretary General of the Organization of American States (OAS), Luis Almagro, also expressed concern over the apparent inability of the Haitian parliamentarians to meet in the National Assembly to decide on the best way to ensure institutional stability and encourage the continuation of the electoral process.

"Given the importance of the serious challenges and risks to the stability of the country, it is particularly disturbing that the meeting of the National Assembly scheduled for July 14 was canceled, again due to a failure to achieve a quorum, "Almagro said.

"Haiti can not afford to be held hostage to delaying tactics and other stratagems," he added. "The situation is critical. It's time to make a decision that should have been done long ago.
